How to Make Everlasting Yeast

4 medium potatoes
4 tablespoons sugar

Boil potatoes. Drain and save water. Run boiled potatoes through fruit press or sieve.

To potatoes add enough potato water to make 2/3 quart. Mix in sugar.

Set in warm place until mixture ferments and bubbles form on top.

Use 1 cup each time you bake.

Replenish the yeast by adding potato water and sugar as needed. Store in a tightly covered glass jar in cool place.
