Mix yeast with potato water and set aside to rise. Mix potatoes, oleo, eggs, salt and sugar. Blend in flour, add yeast water; blend well. Place in greased Tupperware bowl and put in refrigerator. Rise as desired. After the dough is cold (overnight), take out, grease hands and pinch off dough, enough for the size of roll you want. Place in pan to rise, double in bulk. Bake at 450°F until golden brown.
