Set a sponge over night, with potatoes or white flour, in the following
proportions:—
1 cup yeast.
6 potatoes, mashed fine with three cups of flour.
1 quart warm water.
2 tablespoonfuls lard (_or_, if you leave out the potatoes, one
quart of warm water to three pints of flour).
2 tablespoonfuls brown sugar.
Beat up well and let it rise five or six hours.
