Because the lightness of cake depends upon bubbles of air or gas which in the course of time collapse, cake batter should be baked as soon as mixed. That this may be possible, the fire should be put into suitable condition and the utensils and materials gathered and prepared before the mixing begins. _Pastry._--Pastry mixtures differ from bread or cake mixtures in that they are flaky instead of spongy. Things flake when they are composed of layers; the point then is to make pastry by a process which will produce layers. When a smooth dough has been made of flour, salt and cold water, it is rolled lightly to a thin sheet, tiny pieces of butter are scattered over it and a very little flour sprinkled on it. The sheet is then doubled, rolled to the former thickness, butter and flour are applied to it as before and it is again doubled. This is repeated several times. When it is finally ready for the oven it is in layers of dough and butter. When the heat of the oven melts the butter and expands the air between the layers, they separate a little, that is, they flake. By means of this theory of pastry one can better understand the directions given in pastry receipts. For example, the ingredients must be kept cold that the butter and dough may not combine during the rolling. The pastry must be handled lightly and never pressed or pounded because this would press out the air and crush the layers into each other. The filling of pies sometimes presents difficulties. A very juicy filling soaks the under crust. One remedy used for this is to bake the bottom crust before filling the pie; another is to brush it over with white of egg. The very best way to prevent the under crust of a pie from being soggy and indigestible is not to have one. Put the fruits into a fairly deep baking-dish and cover it with a flaky top crust. This is an English method which we should do well to follow. The result is more fruit and less crust, and none of that under crust which whatever pains you take will more or less relapse into dough. Juicy pies must not be filled quite full, that they may not boil over in the oven. Openings cut in the crust help to prevent this; an inverted tea cup put into a deep pie is also a preventive. I am told that if the top crust is just laid over the pie and not fastened at the edges, the juice of the filling is less apt to run out. 3. THE SEQUENCE Going into the kitchen to make one dish; or getting a supper for which much of the food has been previously prepared, gives no suggestion of one of the chief difficulties in getting meals. This difficulty is the sequence of work. Unless thoughtful and orderly arrangements are made, one dish will be done too early, another too late, the cook may find she is required to perform two pieces of work at once and the last moments before the meal will be crowded with more things than can possibly be done.
