Boil half a pound of fresh hops in four quarts of water, till the liquid is reduced to two quarts Strain it, and mix in sufficient wheat flour to make a thin batter; adding half a pint of strong fresh yeast, (brewer's yeast, if it can be procured.) When it is done fermenting, pour it into a pan, and stir in sufficient Indian meal to make a moderately stiff dough. Cover it, and set it in a warm place to vise. When it has become very light, roll it out into a thick sheet, and cut it into little cakes. Spread them out on a dish, and let them dry gradually in a cool place where there is no sun. Turn them five or six times a day while drying; and when they are quite dry, put them into paper bags, and keep them in a jar or box closely covered, in a place that is not in the least damp.
When you want the yeast for use, dissolve in a little warm water one or more of the cakes, (in proportion to the quantity of bread you intend making,) and when it is quite dissolved, stir it hard, thicken it with a little flour, cover it, and place it near the fire to rise before you use it. Then mix it with the Hour in the usual manner of preparing bread.
This is a very convenient way of preserving yeast through the summer, or of conveying it to a distance.
