The aim of this book is to present in a convenient form such directions for making and using fireless cookers and similar insulating boxes, that those who are not experienced, even in the ordinary methods of cookery, may be able to follow them easily and with success. The fact that their management has been so little understood has been the cause of failures among the adventurous women who, attracted by their novelty, have tried to experiment with them and have come to the mistaken conclusion that they are not practical, have limited scope, and are altogether a good deal of a disappointment. Such women have made the statement that they are not adapted to cooking starchy foods; that they will not do for most vegetables; that raised breads and puddings cannot be cooked in them, and that there is little economy in using them! It has invariably been found, however, that a better understanding of their management has resulted in complete success, followed inevitably by enthusiasm.

The first few chapters of the book give directions for making and using a cooker, methods of measuring, and some tables for quick reference, followed by a large number of frequently tested recipes, some of which are entirely original, but many of which are based on the well-tried recipes from such books as Miss Farmer’s “Boston Cooking School Cook Book,” Mrs. Lincoln’s “Boston Cook Book,” Miss Smedley’s “Institution Recipes,” and Miss Ronald’s “Century Cook Book,” somewhat modified and adapted to hay-box cookery. “The Fireless Cooker,” by Lovewell, Whittemore, and Lyon, has furnished some excellent ideas, such as the refrigerating box and home-made insulated oven and insulating pail, which have been elaborated in this book. Miss Huntington’s bulletin, “The Fireless Cooker,” has also been suggestive of a number of experiments which are to be found in the Appendix.

The chapter on “Institution Cookery” was introduced in the hope that many small institutions, boarding-house keepers, and those who are managing lunch-rooms, would be induced, by finding recipes arranged in suitable quantities for them, to introduce fireless cookers into their kitchens, and benefit by the great saving in labour and expense which is specially necessary to those who are dependent upon their kitchens for support. When a little experience is gained by using them, it will be found that all the other recipes in the book can be enlarged without minute directions.

It will be noticed that nearly every recipe in the book states how many persons it will serve, the idea being that, in spite of the variable quantities which different people use, this would act as a guide to those who wish to plan rather closely. Where two numbers are given the variation is in proportion to the difference between the amount eaten by men and by women.

The Appendix describes or suggests a series of experiments illustrating the scientific as well as the practical side of fireless cookery. Many of them would be easy for the average housekeeper to carry out, and would illuminate the subject to an extent which would repay her; but they are specially planned for students of household economics who have time and opportunity for such work, and who are supposed to know more than mere methods of housework, and to require an explanation of the principles involved.
