1 sm. potato
Dash of salt
1 tbsp. butter
1 lb. confectioners' sugar
1 tsp. vanilla
Peanut butter

Peel cooked potato. Mash with salt and butter. Add sugar, 1/3 at a time, beating until smooth and well blended. Mix in vanilla. If mixture is not stiff enough to roll, add more sugar. Roll out between 2 sheets of wax paper until 1/8 inch thick. Spread peanut butter. Roll up like a jelly roll. Chill for an hour, then slice. Keep chilled.
