DRIED CORN MEAL YEAST CAKES.—Half a pound of fresh hops.—Four quarts of water.—A pint of wheat or rye flour.—Half a pint of strong fresh yeast, from the brewer or baker.—Three pints, or more of Indian meal. Boil half a pound of fresh hops in four quarts of water, till the liquid is reduced to two quarts. Strain it into a pan, and mix in sufficient wheat flour to make a thin batter; adding half a pint of the best yeast you can procure. Leave it to ferment; and when the fermentation is over, stir in sufficient Indian meal to make a moderately stiff dough. Cover it, and set in a warm place to rise. When it has become very light, roll it out into a square sheet an inch thick, and cut it into flat cakes, about four inches square. Spread them out separately, on a large dish; and let them dry slowly, in a cool place where there is no sun. While drying, turn them five or six times a-day. When they are quite dry and hard, put them separately into brown paper bags, and keep them in a box closely covered, and in a place not the least damp.
When you want them to use for yeast, dissolve in a little warm water, one or more of the cakes, in proportion to the quantity of bread you intend making. When it is quite dissolved, stir it hard, thicken it with a little wheat flour, cover it, and place it near the fire to rise, before you use it. Then mix it with the flour, according to the usual manner of making bread. One yeast cake is enough for two quarts of meal or flour.
This way of preserving yeast is very convenient for keeping through the summer; or for conveying to a distance.
EXCELLENT HOME-MADE YEAST.—Yeast should always be kept in a glass bottle or a stone jug, and never in earthen or metal. Before you make fresh yeast, empty entirely the vessel that has contained the last; and if of stone, scald it twice with boiling water, in which it will be well to mix a little clear lye. Then rinse it with cold water, till perfectly clean. If you have not used lye in scalding it, dissolve some potash or pearlash in the rinsing-water, to remove any acidity that may linger about the vessel, and may therefore spoil the new yeast. If you keep your yeast in glass bottles, the water must be warm, but not hot; as scalding water may crack them: also melt some potash or pearlash in this water. The vessel for keeping it being purified, proceed to make your yeast. Have ready, in a kettle over the fire, two quarts of boiling water; put into it a very large handful of hops, (as fine and fresh as possible,) and let the water boil again with the hops in it, for twenty minutes or more. Sift into a pan three pints of wheat flour. Strain the liquor from the hops into a large bowl, and pour half of it hot over the flour. Stir it well, and press out all the lumps till it is quite smooth. Let the other half of the liquid stand till it is cool, and then pour it gradually to the rest; mixing it well, by stirring as you proceed. Then take half a pint of good strong yeast—brewers’ or bakers’ yeast, if you can get it fresh; if not, you must use some that has been left from your last making, provided it is not the least sour; stir this yeast into the mixture of hop-water and flour; put it immediately into your jug or bottles, and cork it loosely till the fermentation is over, (which should be in an hour,) and it will then be fit for use. Afterwards cork it tightly. It will keep better if you put a raisin or two into the bottom of each bottle, before you pour in the fresh yeast. Into a stone jug put half a dozen raisins.
All yeast is better and more powerful for being fresh. It is better to make it frequently, (the trouble being little,) than to risk its becoming sour by endeavouring to keep it too long. When sour, it becomes weak and watery, and tastes and smells disagreeably, and will never make light bread; besides being very unwholesome. The acidity may be somewhat corrected by stirring in some dissolved pearlash, sal-eratus, or soda, immediately before the yeast is used; but it is better to have it good and fresh, without the necessity of any corrective. Yeast should always be kept in a cool place.
Those who live in towns where there are breweries have no occasion to make their own yeast during the brewing season; and in summer they can every day supply themselves with fresh yeast from the baker’s. It is only in country places where there are neither brewers nor bakers that it is expedient to make it at home. For home-made yeast, we know the above receipt to be excellent.
Sweet cakes, buns, rusks, &c., require stronger and fresher yeast than bread; the sugar will otherwise retard their rising.
