How to Make It
Cook potatoes in boiling water to over 10 minutes or until tender. Drain potatoes, reserving 1 cup liquid (add water to make 1 cup, if necessary). Mash potatoes; add reserved liquid to potatoes, and set aside.
Dissolve yeast in warm water; let stand 5 minutes, and set aside. Beat eggs; add enough milk to eggs to equal1 cup liquid, and set aside.
Combine shortening, sugar, and salt in a saucepan; cook over low heat, stirring constantly, until shortening melts. Cool to 105° to 115°; stir in potatoes, egg mixture, and yeast mixture. Gradually stir in enough flour to make a soft dough.
