by Woman's Inst.i.tute of Domestic Arts and Sciences.

PREFACE

The Woman's Inst.i.tute Library of Cookery consists of five volumes that cover the various phases of the subject of cookery as it is carried on in the home. These books contain the same text as the Instruction Papers of the Inst.i.tute's Course in Cookery arranged so that related subjects are grouped together. Examination questions pertaining to the subject matter appear at the end of each section. These questions will prove helpful in a mastery of the subjects to which they relate, as they are the same as those on which students of the Inst.i.tute are required to report. At the back of each volume is a complete index, which will a.s.sist materially in making quick reference to the subjects contained in it.

This volume, which is the first of the set, deals with the essentials of cookery, cereals, bread, and hot breads. In _Essentials of Cookery_, Parts 1 and 2, are thoroughly treated the selection, buying, and care of food, as well as other matters that will lead to familiarity with terms used in cookery and to efficiency in the preparation of food. In _Cereals_ are discussed the production, composition, selection, and care and the cooking and serving of cereals of all kinds. In _Bread_ and _Hot Breads_ are described all the ingredients required for bread, rolls, and hot breads of every kind, the processes and recipes to be followed in making and baking them, the procedure in serving them, and the way in which to care for such foods.

Whenever advisable, utensils for the preparation of food, as well as labor-saving devices, are described, so as to enable beginners in the art of cookery to become acquainted with them quickly. In addition, this volume contains breakfast, luncheon, and dinner menus that will enable the housewife to put into practical, every-day use many of the recipes given.

It is our hope that these volumes will help the housewife to acquire the knowledge needed to prepare daily meals that will contain the proper sustenance for each member of her family, teach her how to buy her food judiciously and prepare and serve it economically and appetizingly, and also instil in her such a liking for cookery that she will become enthusiastic about mastering and dignifying this womanly art.

ESSENTIALS OF COOKERY (PART 1)

THE PROBLEM OF FOOD

1. Without doubt, the greatest problem confronting the human race is that of food. In order to exist, every person must eat; but eating simply to keep life in the body is not enough. Aside from this, the body must be supplied with an ample amount of energy to carry on each day's work, as well as with the material needed for its growth, repair, and working power. To meet these requirements of the human body, there is nothing to take the place of _food_, not merely any kind, however, but the _right_ kind. Indeed, so important is the right kind of food in the scheme of life that the child deprived of it neither grows nor increases in weight, and the adult who is unable to secure enough of it for adequate nourishment is deficient in nerve force and working power. If a person is to get the best out of life, the food taken into the body must possess real sustaining power and supply the tissues with the necessary building material; and this truth points out that there are facts and principles that must be known in order that the proper selection of food may be made, that it may be so prepared as to increase its value, and that economy in its selection, preparation, use, and care may be exercised.

2. Probably the most important of these principles is the _cooking of food_. While this refers especially to the preparation of food by subjecting edible materials to the action of heat, it involves much more. The cooking of food is a science as well as an art, and it depends for its success on known and established principles. In its full sense, _cookery_ means not only the ability to follow a recipe, thereby producing a successfully cooked dish, but also the ability to select materials, a knowledge of the ways in which to prepare them, an understanding of their value for the persons for whom they are prepared, and ingenuity in serving foods attractively and in making the best use of food that may be left over from the previous meals, so that there will be practically no waste. Thus, while cookery in all its phases is a broad subject, it is one that truly belongs to woman, not only because of the pleasure she derives in preparing food for the members of her family, but because she is particularly qualified to carry on the work.

3. The providing of food in the home is a matter that usually falls to the lot of the housewife; in fact, on her depends the wise use of the family income. This means, then, that whether a woman is earning her own livelihood and has only herself to provide for, or whether she is spending a part of some other person's income, as, for instance, her father's or her husband's, she should understand how to proportion her money so as to provide the essential needs, namely, food, clothing, and shelter. In considering the question of providing food, the housewife should set about to determine what three meals a day will cost, and in this matter she should be guided by the thought that the meals must be the best that can possibly be purchased for the amount of money allowed for food from the family income and that their cost must not exceed the allotment. To a great extent she can control the cost of her foods by selecting them with care and then making good use of what her money has bought. It is only by constant thought and careful planning, however, that she will be able to keep within her means, and she will find that her greatest a.s.sistance lies in studying foods and the ways in which to prepare them.

4. A factor that should not be disregarded in the problem of food is _waste_, and so that the housewife can cope with it properly she should understand the distinction between waste and refuse. These terms are thought by some to mean the same thing and are often confused; but there is a decided difference between them. _Waste_, as applied to food, is something that could be used but is not, whereas _refuse_ is something that is rejected because it is unfit for use. For example, the fat of meat, which is often eaten, is waste if it is thrown away, but potato parings, which are not suitable as food, are refuse.

In connection with the problem of waste, it may be well to know that leakage in the household is due to three causes. The first one is lack of knowledge on the part of the housekeeper as to the difference between waste and refuse and a consequent failure to market well. As an ill.u.s.tration, many housewives will reject turkey at a certain price a pound as being too expensive and, instead, will buy chicken at, say, 5 cents a pound less. In reality, chicken at 5 cents a pound less than the price of turkey is more expensive, because turkey, whose proportion of meat to bone is greater than that of chicken, furnishes more edible material; therefore, in buying chicken, they pay more for refuse in proportion to good material. The second cause for this leakage in the household is excessive waste in the preparation of food for the table, arising from the selection of the wrong cooking method or the lack of skill in cooking; and the third cause is the serving of too large quant.i.ties and a consequent waste of food left on individual plates and unfit for any other use in the home.

5. Another matter that constantly confronts the housewife is what foods she shall select for each day's meals. To be successful, all meals should be planned with the idea of making them wholesome and appetizing, giving them variety, and using the left-overs. Every woman should understand that food is cooked for both hygienic and esthetic reasons; that is, it must be made safe and wholesome for health's sake and must satisfy the appet.i.te, which to a considerable degree is mental and, of course, is influenced by the appearance of the food. When the housewife knows how to cook ordinary foods well, she has an excellent foundation from which to obtain variety in the _diet_--by which in these lessons is meant the daily food and drink of any individual, and not something prescribed by a physician for a person who is ill--for then it is simply a matter of putting a little careful thought into the work she is doing in order to get ideas of new ways in which to prepare these same foods and of utilizing foodstuffs she has on hand. However, ample time must always be allowed for the preparation of meals, for no one can expect to produce tasty meals by rushing into the kitchen just before meal time and getting up the easiest thing in the quickest manner. Well-planned meals carefully prepared will stimulate interest in the next day's bill of fare and will prove extremely beneficial to all concerned.

6. In the practice of cookery it is also important that the meals be planned and the cooking done for the sake of building the human body and caring for it. As soon as any woman realizes that both the present and the future welfare of the persons for whom she is providing foods depend on so many things that are included in cookery, her interest in this branch of domestic science will increase; and in making a study of it she may rest a.s.sured that there is possibly no other calling that affords a more constant source of enjoyment and a better opportunity for acquiring knowledge, displaying skill, and helping others to be well and happy.

The fact that people constantly desire something new and different in the way of food offers the housewife a chance to develop her ingenuity along this line. Then, too, each season brings with it special foods for enjoyment and nourishment, and there is constant satisfaction in providing the family with some surprise in the form of a dish to which they are unaccustomed, or an old one prepared in a new or a better way.

But the pleasure need not be one-sided, for the adding of some new touch to each meal will give as much delight to the one who prepares the food as to those who partake of it. When cookery is thought of in this way, it is really a creative art and has for its object something more than the making of a single dish or the planning of a single meal.

7. From what has been pointed out, it will readily be seen that a correct knowledge of cookery and all that it implies is of extreme importance to those who must prepare food for others; indeed, it is for just such persons--the housewife who must solve cookery problems from day to day, as well as girls and women who must prepare themselves to perform the duties with which they will be confronted when they take up the management of a household and its affairs--that these lessons in cookery are intended.

In the beginning of this course of study in cookery it is deemed advisable to call attention to the order in which the subject matter is presented. As will be seen before much progress is made, the lessons are arranged progressively; that is, the instruction begins with the essentials, or important fundamentals, of food--its selection, preparation, and care--and, from these as a foundation, advances step by step into the more complicated matters and minor details. The beginner eager to take up the actual work of cookery may feel that too much attention is given to preliminaries. However, these are extremely essential, for they are the groundwork on which the actual cooking of food depends; indeed, without a knowledge of them, very little concerning cookery in its various phases could be readily comprehended.

8. Each beginner in cookery is therefore urged to master every lesson in the order in which she receives it and to carry out diligently every detail. No lesson should be disregarded as soon as it is understood, for the instruction given in it bears a close relation to the entire subject and should be continually put into practice as progress is made. This thought applies with particular emphasis to the Sections relating to the essentials of cookery. These should be used in connection with all other Sections as books of reference and an aid in calling to mind points that must eventually become a part of a woman's cookery knowledge. By carrying on her studies systematically and following directions carefully, the beginner will find the cooking of foods a simple matter and will take delight in putting into practice the many things that she learns.

SELECTION OF FOOD

MATTERS INVOLVED IN RIGHT SELECTION

9. Each one of the phases of cookery has its importance, but if success is to be achieved in this art, careful attention must be given to the selection of what is to be cooked, so as to determine its value and suitability. To insure the best selection, therefore, the housewife should decide whether the food material she purchases will fit the needs of the persons who are to eat it; whether the amount of labor involved in the preparation will be too great in proportion to the results obtained; whether the loss in preparation, that is, the proportion of refuse to edible matter, will be sufficient to affect the cost materially; what the approximate loss in cooking will be; whether the food will serve to the best advantage after it is cooked; and, finally, whether or not all who are to eat it will like it. The market price also is a factor that cannot be disregarded, for, as has been explained, it is important to keep within the limits of the amount that may be spent and at the same time provide the right kind of nourishment for each member of the family.

10. In order to select food material that will meet the requirements just set forth, three important matters must be considered; namely, the _substances_ of which it is composed; its measure of energy-producing material, or what is called its _food_, or _fuel, value_; and its _digestion_ and _absorption_. Until these are understood, the actual cost of any article of food cannot be properly determined, although its price at all times may be known.

However, before a study of any of these matters is entered into, it is necessary to know just what is meant by food and what food does for the body. As is well understood, the body requires material by which it may be built and its tissues repaired when they are torn down by work and exercise. In addition it requires a supply of heat to maintain it at normal temperature and provide it with sufficient energy to do the work required of it. The material that will accomplish these important things is food, which may therefore be regarded as anything that, when taken into the body, will build and repair its tissues or will furnish it with the energy required to do its work.

FOOD SUBSTANCES

11. Although, as has just been stated, food may be considered as anything that the human engine can make over into tissue or use in living and working, not all foods are equally desirable any more than all materials are equally good in the construction of a steam engine and in the production of its working power. Those food substances which are the most wholesome and healthful are the ones to be chosen, but proper choice cannot be made unless the buyer knows of what the particular food consists and what it is expected to do. To aid in the selection of food, therefore, it is extremely necessary to become familiar with the five substances, const.i.tuents, or principles of which foods are made up; namely, water, mineral matter, or ash, protein, fat, and carbohydrate. A knowledge of these will help also in determining the cooking methods to adopt, for this depends on the effect that heat has on the various substances present in a food. Of course, so far as flavor is concerned, it is possible for the experienced cook to prepare many dishes successfully without knowing the effect of heat on the different food const.i.tuents; but to cook intelligently, with that success which makes for actual economy and digestibility, certain facts must be known concerning the food principles and the effect of dry and moist heat on foods.

12. Water.--Of the various const.i.tuents that are found in the human body, water occurs in the largest quant.i.ty. As a food substance, it is an extremely important feature of a person's diet. Its chief purpose is to replenish the liquids of the body and to a.s.sist in the digestion of food. Although nature provides considerable amounts of water in most foods, large quant.i.ties must be taken in the diet as a beverage. In fact, it is the need of the body for water that has led to the development of numerous beverages. Besides being necessary in building up the body and keeping it in a healthy condition, water has a special function to perform in cooking, as is explained later. Although this food substance is extremely essential to life, it is seldom considered in the selection of food, because, as has just been mentioned, nearly all foods contain water.

13. Mineral Matter.--Ranking next to water in the quant.i.ty contained in the human body is mineral matter. This const.i.tuent, which is also called _ash_ or _mineral salts_, forms the main part of the body's framework, or skeleton. In the building and maintaining of the body, mineral salts serve three purposes--to give rigidity and permanence to the skeleton, to form an essential element of active tissue, and to provide the required alkalinity or acidity for the digestive juices and other secretions.

The origin and distribution of these mineral substances are of interest.

Plants in their growth seize from the earth the salts of minerals and combine them with other substances that make up their living tissue.

Then human beings, as well as other living creatures, get their supply of these needed salts from the plants that they take as food, this being the only form in which the salts can be thoroughly a.s.similated. These salts are not affected by cooking unless some process is used that removes such of them as are readily soluble in water. When this occurs, the result is usually waste, as, for instance, where no use is made of the water in which some vegetables are boiled. As is true of water, mineral matter, even though it is found in large quant.i.ties in the body, is usually disregarded when food is purchased. This is due to the fact that this important nutritive material appears in some form in nearly all foods and therefore does not necessitate the housewife's stopping to question its presence.

14. Protein.--The food substance known as protein is a very important factor in the growth and repair of the body; in fact, these processes cannot be carried on unless protein is present in the diet. However, while a certain quant.i.ty of protein is essential, the amount is not very large and more than is required is likely to be harmful, or, since the body can make no use of it, to be at least waste material. The princ.i.p.al sources of protein are lean meat, eggs, milk, certain grains, nuts, and the legumes, which include such foods as beans and peas. Because of the ease with which they are digested, meat, fish, eggs, and milk are more valuable sources of protein than bread, beans, and nuts. However, as the foods that are most valuable for proteins cost more than others, a mixed diet is necessary if only a limited amount of money with which to purchase foods is available.

15. So much is involved in the cooking of foods containing protein that the effect of heat on such foods should be thoroughly understood. The cooking of any food, as is generally understood, tends to break up the food and prepare it for digestion. However, foods have certain characteristics, such as their structure and texture, that influence their digestibility, and the method of cooking used or the degree to which the cooking is carried so affects these characteristics as to increase or decrease the digestibility of the food. In the case of foods containing protein, unless the cooking is properly done, the application of heat is liable to make the protein indigestible, for the heat first coagulates this substance--that is, causes it to become thick--and then, as the heat increases, shrinks and hardens it. This fact is clearly demonstrated in the cooking of an egg, the white of which is the type of protein called _alb.u.min_. In a raw egg, the alb.u.min is nearly liquid, but as heat is applied, it gradually coagulates until it becomes solid. If the egg is cooked too fast or too long, it toughens and shrinks and becomes less palatable, less attractive, and less digestible. However, if the egg is properly cooked after the heat has coagulated the alb.u.min, the white will remain tender and the yolk will be fine and mealy in texture, thus rendering it digestible.

Similar results, although not so evident to the sight, are brought about through the right or wrong way of cooking practically all other foods that contain much protein. Milk, whose princ.i.p.al ingredient is a protein known as _casein_, familiar as the curd of cheese, ill.u.s.trates this fact very plainly. When it is used to make cottage cheese, heating it too long or to too high a degree will toughen the curd and actually spoil the texture of the product, which will be grainy and hard, instead of smooth and tender.

16. FATS.--The food substances just discussed--water, mineral matter, and protein--yield the materials required for building and repairing the tissues of the body, but, as has been explained, the body also requires foods that produce energy, or working power. By far the greater part of the total solids of food taken into the body serve this purpose, and of these fats form a large percentage. Although fats make up such a large proportion of the daily food supply, they enter into the body composition to a less extent than do the food substances that have been explained. The fats commonly used for food are of both animal and vegetable origin, such as lard, suet, b.u.t.ter, cream, olive oil, nut oil, and cottonseed oil. The ordinary cooking temperatures have comparatively little effect on fat, except to melt it if it is solid. The higher temperatures decompose at least some of it, and thus liberate substances that may be irritating to the digestive tract.

17. CARBOHYDRATES.--Like fats, the food substances included in the term carbohydrates supply the body with energy. However, fats and carbohydrates differ in the forms in which they supply energy, the former producing it in the most concentrated form and the latter in the most economical form.

So that the term _carbohydrate_ may be clearly understood and firmly fixed in the mind, it is deemed advisable to discuss briefly the composition of the body and the food that enters it. Of course, in a lesson on cookery, not so much attention need be given to this matter as in a lesson on _dietetics_, which is a branch of hygiene that treats of diet; nevertheless, it is important that every person who prepares food for the table be familiar with the fact that the body, as well as food, is made up of a certain number of chemical elements, of which nitrogen, carbon, hydrogen, and oxygen form a large part. Protein owes its importance to the fact that of the various food substances it alone contains the element nitrogen, which is absolutely essential to the formation of any plant or animal tissue. The other three elements, carbon, hydrogen, and oxygen, go to make up the carbohydrates; in fact, it is from the names of these three elements that the term carbohydrate is derived. The carbohydrates include the starches and sugars that are used and eaten in so many forms, and these contain the three elements mentioned, the hydrogen and oxygen contained in them being in the proportion that produces water. Thus, as will readily be seen, by separating the name into its parts--_carbo_ (carbon) and _hydrate_ (hydrogen and oxygen in the proportion of two parts of hydrogen and one of oxygen, that is, in the form of water)--carbohydrate is simply carbon united with water. While the facts just brought out have much to do with food economy, they are of interest here chiefly because they help to make clear the term carbohydrate, which, as will be admitted, is the only correct name for the food substance it represents.

18. STARCH, one of the chief forms of carbohydrates, is found in only the vegetable kingdom. It is present in large quant.i.ties in the grains and in potatoes; in fact, nearly all vegetables contain large or small amounts of it. It is stored in the plant in the form of granules that lie within the plant cells.

Cooking applied to starch changes it into a form that is digestible.

Moist heat cooks the granules until they expand and burst and thus thicken the ma.s.s. Dry heat changes starch first into a soluble form and finally into what is called _dextrine_, this being the intermediate step in the changing of starch into sugar.

19. SUGAR, another important form of carbohydrate, is mainly of vegetable origin, except that which is found in milk and called _lactose_. This, together with the fat found in milk, supplies the child with energy before it is able to digest a variety of foods. The sap of various plants contains such large quant.i.ties of sugar that it can be crystalized out and secured in dry form. The liquid that remains is valuable as food, for, by boiling it down, it forms mola.s.ses. Sugar is also present in considerable amounts in all fruits, and much of it is in a form that can be a.s.similated, or taken up by the body, quickly. A sugar very similar to this natural fruit sugar is made from the starch of corn and is called _glucose_. Much of the carbohydrate found in vegetables, especially young, tender vegetables, is in the form of sugar, which, as the vegetables grow older, changes to starch.

Sugar melts upon the application of heat or, if it is in a melted condition, as sirup or mola.s.ses, it boils down and gives off water. When all the water has boiled away, the sugar begins to caramelize or become brown, and develops a characteristic flavor. If the cooking is continued too long, a dark-brown color and a bitter taste are developed. Because the sugar in fruits and vegetables is in solution, some of it is lost when they are boiled, unless, of course, the water in which they are cooked is utilized.

20. CELLULOSE is a form of carbohydrate closely related to starch. It helps to form the structure of plants and vegetables. Very little cellulose is digested, but it should not be ignored, because it gives the necessary bulk to the food in which it occurs and because strict attention must be paid to the cooking of it. As cellulose usually surrounds nutritive material of vegetable origin, it must be softened and loosened sufficiently by cooking to permit the nutritive material to be dissolved by the digestive juices. Then, too, in old vegetables, there is more starch and the cellulose is harder and tougher, just as an old tree is much harder than a sapling. This, then, accounts for the fact that rapid cooking is needed for some vegetables and slow cooking for others, the method and the time of cooking depending on the presence and the consistency of the cellulose that occurs in the food.

21. IMPORTANCE OF A VARIETY OF FOODS.--Every one of the five food substances just considered must be included in a person's diet; yet, with the exception of milk, no single food yields the right amounts of material necessary for tissue building and repair and for heat and energy. Even milk is in the right proportion, as far as its food substances are concerned, only for babies and very young children. It will thus be seen that to provide the body with the right foods, the diet must be such as to include all the food substances. In food selection, therefore, the characteristics of the various food substances must be considered well. Fats yield the most heat, but are the most slowly digested. Proteins and carbohydrates are more quickly digested than fats, but, in equal amounts, have less than half as much food value. Water and mineral salts do not yield heat, but are required to build tissue and to keep the body in a healthy condition. In addition, it is well to note that a well-balanced diet is one that contains all of the five food substances in just the right proportion in which the individual needs them to build up the body, repair it, and supply it with energy. What this proportion should be, however, cannot be stated offhand, because the quant.i.ty and kind of food substances necessarily vary with the size, age, and activity of each person.

FOOD VALUE

22. Nearly all foods are complex substances, and they differ from one another in what is known as their _value_, which is measured by the work the food does in the body either as a tissue builder or as a producer of energy. However, in considering food value, the person who prepares food must not lose sight of the fact that the individual appet.i.te must be appealed to by a sufficient variety of appetizing foods. There would be neither economy nor advantage in serving food that does not please those who are to eat it.
