1/2 Medium Sized Potato
1 Box Confectioners Sugar
Boil medium sized potato. Put in fridge to get cold.
Remove potato skin and use a fork to mash. Potato should be watery.
Add the entire box of confectioners sugar.
Once thoroughly mixed and very stiff, roll out mixture on a piece of waxed paper that has been dusted with confectioners sugar. Spread with peanut butter and roll as a jelly roll.
Roll should be no wider than quarter-sized. Cut pieces as desired.
