At 6 o'clock in the morning place in a bowl 1 cup of finely-mashed
(boiled) potatoes (the cup of left-over mashed potatoes may be used as
a matter of economy). Add 1 cup of potato water (the water drained
from boiled potatoes), in which 1/2 cake of Fleischman's yeast had
been dissolved, add 1 cup of flour and 1 teaspoon of sugar. Stand in a
warm place to raise, from 1 to 1-1/4 hours. At the expiration of that
time add to the foamy sponge 1 large tablespoonful
f butter or lard,
1 egg and 1/2 teaspoonful of salt, beaten together before adding. Add
about 2 cups of flour, beat thoroughly and allow to raise another
hour; then roll out the dough about 1 inch in thickness and cut into
small biscuits, dip each one in melted butter and place on pans, a
short distance apart, stand about one hour to raise, when bake in a
rather hot oven. These Potato Biscuits are particularly nice when
freshly baked, and resemble somewhat biscuits made from baking powder.
From this recipe was made two dozen biscuits.
