Mashed Potato Refrigerator Rolls

Aunt Julia made these often and they are so good.

Mashed Potato Refrigerator Rolls
1 pkg yeast
1/2 cup warm water
1 cup oil
1 cup cold water
3/4 cup sugar
1 cup mashed potatoes (I use left overs or you can mash a cup full)
1-1/2 tsp salt
6 or 6-1/2 cup flour

In large bowl, sprinkle yeast into warm water, stirring until dissolved. Stir in oil, sugar, potatoes, then cold water, salt and enough flour to make stiff dough. Place dough in large greased bowl, cover with greased wax or foil paper, then a clean towel, refrigerate. Shape as preferred. Let rise until double in size. Bake 20 to 25 minutes in 425 degree oven. Makes 3 or 3-1/2 dozen rolls. (Sometimes I cut mine in pie wedge pieces with pizza cutter, roll from wide end to small end and make crescents).
