Yeast ( Potato. ) ✠
6 potatoes.
2 quarts cold water.
4 tablespoonfuls flour.
2 tablespoonfuls white sugar.
Peel and boil the potatoes until they break. Leaving the water on the fire, take them out and mash fine with the flour and sugar, wetting gradually with the hot water until it is all used. When lukewarm, add a gill of good yeast, and set aside in an open vessel and warm place to ferment. When it ceases to effervesce, bottle and set in ice-house.
This yeast is very nice and white, and is preferred by many who dislike the bitter taste of hops. It is also convenient to make when hops cannot be obtained.
