21. GRIDDLES.--A style of griddle in common use is illustrated in Fig. 3, and while it is circular and has a projecting handle, griddles of different shapes and fitted with different handles are to be had. Such utensils are made of numerous materials, but the most satisfactory ones are constructed of steel, iron, soapstone, and aluminum. Steel and iron griddles must be greased before cakes are baked on them so as to prevent the cakes from sticking; for this reason they are less convenient than soapstone and aluminum griddles, which do not require any grease.
The size of griddle to use is governed by the number of persons that are to be served. One that is unusually large, however, should be avoided if a gas stove is used for cooking, as it is difficult to heat a large griddle evenly on such a stove, and even a small one must be shifted frequently so that some spots will not be hotter than others. In this respect, a griddle made of aluminum has the advantage over the other kinds, for this material conducts the heat evenly over its entire surface.
Before a new steel or iron griddle is used, it must be tempered so as to prevent the food that is to be baked on it from sticking. If it is not tempered, much time will be consumed before its surface will be in the right condition to permit baking to proceed without difficulty, and this, of course, will result in wasting considerable food material. Tempering may be done by covering the griddle with a quantity of fat, placing it over a flame or in a very hot oven, and then allowing it to heat thoroughly to such a temperature that the fat will burn onto the surface. This same precaution should be observed with new waffle irons and frying pans made of steel or iron if the best results from such utensils are desired.
22. WAFFLE IRONS.--A waffle iron, as shown in Figs. 4 and 5, consists of two corrugated griddles fastened together with a hinge in such a way that the surfaces nearly touch when the handles are brought together as in Fig. 4 (a). These griddles are so suspended in a frame that they may be turned completely over in order to allow each side to be exposed to the heat. The waffle iron illustrated in Fig. 4, shown closed in view (a) and open in (b), is intended for a coal range. In order to use it, a stove lid is removed from one of the openings and the waffle iron is set in the opening, which allows the griddle part to be turned. The waffle iron shown in Fig. 5 is intended for a gas range. As will be noticed, the griddle part rests on a base that is deep enough to permit it to be turned. In using a waffle iron of either kind, it should be heated while the waffle mixture is being prepared; then it should be thoroughly greased on both sides. No excess fat, however, should be used, as it will run out when the griddle is turned over.
THE MIXTURE
VARIETIES OF MIXTURES AND GENERAL PROPORTIONS
23. BATTERS AND DOUGHS.--The mixtures from which hot breads are produced are of different consistencies, and familiarity with them is necessary if good results in the making of such breads are desired. This difference in the consistencies is due to the proportion of flour and liquid used, a small proportion of flour producing a batter and a large proportion, a dough. It will be well to note, however, that some kinds of flour thicken a mixture much more readily than do others. Experience in the handling of flour teaches how to vary the other ingredients of a recipe in order to make them correspond to the difference in flour, but the person who lacks a knowledge of cookery, or has had very little experience in the handling of foods, must know the general proportions that are correct under most circumstances. The names of the mixtures that the ingredients produce are thin batter, thick batter, soft dough, and stiff dough.
