If you cannot obtain good yeast, and wish to have the cakes ready with as much expedition as possible, you may use patent yeast-powders, according to the directions that accompany them. In this case, the cakes must be baked in half an hour after the powders are mixed into the batter.
Yeast-powders, put in at the last, are an improvement to all sorts of batter-cakes that have been previously raised with good _real_ yeast; also to cakes made light by eggs. But to depend _entirely_ on the powders, without either real yeast, or eggs, is not well; as the cakes, though _eatable_, are generally too tough and leathery to be wholesome. In cities, fresh yeast, from the brewers, can be obtained every day, at a very trifling cost, during the brewing season; which is usually from October till April. At other seasons, it can be procured from the bakers, or made at home; and should always be used in preference to depending solely on yeast-powders. Though they improve the lightness of batter, for which real yeast or beaten eggs have already been used, they will not, of themselves alone, give it a wholesome degree of either lightness or crispness. Too much dependence on yeast-powders is one reason that the buckwheat-cakes of the present day are so inferior to those of former times, when they were always made with real yeast.
Indian batter-cakes may be made as above.
HARLEM CAKES.--Sift into a pan three pints of flour. Warm, in a sauce-pan, a pint of milk, and cut up in it half a pound of fresh butter. When the butter is soft enough to mix with the milk, stir them well together, and remove the sauce-pan from the fire. Beat three eggs, very light, and mix them with the milk and butter, after they have cooled. Then make a hole in the middle of the flour, and pour in the mixture, and two large table-spoonfuls of strong fresh yeast. With a spoon, mix the flour into the liquid, till the whole is thoroughly incorporated. Then cover the pan with a thick woollen cloth, and set it near the fire, to rise. It should be light in about five hours; perhaps sooner. When quite light, mix in a tea-spoonful of soda, dissolved in a very little warm water; divide the dough into long oval cakes, or rolls; knead each separately. Sprinkle an iron baking-pan with flour; put in the cakes; cover the pan, and let it stand half an hour before baking. Bake the cakes in a moderate oven. Eat them fresh, with butter. They are excellent tea cakes. Of course, they must be mixed in the forenoon.
