Steep the coffee in the milk for 15 minutes. Strain and add the flour and sugar, which have been thoroughly mixed. Cook until the mixture is thickened, stirring constantly to prevent lumps from forming. Add the butter and vanilla, cool, and fill into the éclairs. Cover the top of the éclairs with icing made by thickening a little strong coffee with pulverized sugar.

CARAMEL FILLING FOR ÉCLAIRS

Caramelize 1/2 cupful of the sugar, add the water, and cook until the caramel has dissolved. Mix the remainder of the sugar with the flour and moisten with the milk. Add this to the caramel and cook until the flour thickens completely, stirring constantly to prevent the formation of lumps. Add the butter and vanilla. Cool and fill into the éclairs. Cover the tops with a plain caramel icing.

DOUGHNUTS AND CRULLERS

27. NATURE OF DOUGHNUTS AND CRULLERS.--Some kinds of doughnuts and crullers are made of bread dough, and for this reason really belong to breakfast breads instead of to cakes. However, most of the recipes for these two foods include sugar, shortening, milk, eggs, and leavening, making doughnuts and crullers so similar to cake in their composition that they are usually regarded as cake mixtures. The shortening, which is in smaller amounts than is required for most cakes, is supplied largely by the method of preparation peculiar to these cakes; that is, by their being fried in deep fat. Consequently, some of the same conditions apply in their preparation as in the making of other foods that are cooked in this way. As has already been learned, such foods must either contain a sufficient amount of protein material, such as egg, for instance, or be coated with enough material of this kind to prevent the absorption of fat. In the case of doughnuts, this material is supplied as an ingredient.

28. SHAPING DOUGHNUTS AND CRULLERS.--The ingredients used in the making of doughnuts are combined in much the same way as those used in other cake mixtures. A point to remember is that the mixture, like that for cookies, must be stiff enough to handle and roll out, but care should be taken not to use too much flour, for then the doughnuts are likely to be tough. Divide the dough into amounts of a convenient size, place one of these on a well-floured board, and roll out with a rolling pin until about 1/4 inch thick. Then, with a doughnut cutter, as shown in Fig. 21, cut as many doughnuts as possible from the rolled dough. If a regular doughnut cutter is not in supply, a round cookie cutter may be used and then a thimble or some other small round cutter applied to remove the center of the pieces thus cut. As here shown, a plate or some other small dish containing flour should be kept handy and the cutter dipped into this occasionally during the cutting to prevent it from sticking to the dough and marring the appearance of the doughnuts. Collect the centers and scraps that remain after the doughnuts have been cut from a piece and set these aside until all the fresh dough has been used. These may then be rolled out again and cut into doughnuts. If desired, however, the centers may be fried.

29. While doughnuts are usually round and have a hole in the center, they may, for variety, be made in other shapes. For instance, after the dough is rolled out, it is sometimes cut with a sharp knife Into rectangular pieces about 4 inches long and 2-1/2 inches wide and each one of these pieces then cut lengthwise into three strips attached at one end. When cut in this way, the strips are braided and then pinched together at the loose end. Or, the pieces may be made 4 inches long and 2 inches wide, cut into two strips attached at one end, and the strips then twisted around each other and pinched together at the loose end.
