Bread Sponge (Potato.) ✠
- 6 potatoes, boiled and mashed fine while hot.
- 6 tablespoonfuls baker’s yeast.
- 2 tablespoonfuls white sugar.
- 2 tablespoonfuls lard.
- 1 even teaspoonful soda.
- 1 quart warm—not hot—water.
- 3 cups flour.
Mash the potatoes, and work in the lard and sugar. Stir to a cream, mixing in gradually a quart of the water in which the potatoes were boiled, which should have been poured out to cool down to blood warmth. Beat in the flour, already wet up with a little potato-water to prevent lumping, then the yeast, lastly the soda. Cover lightly if the weather is warm, more closely in winter, and set to rise over night in a warm place.
