Mashed potato fudge
Ingredients
2 sq. unsweetened chocolate
4 tbs. butter
1/3 c. mashed potato (unseasoned)
1/8 tsp. salt
1 tsp. vanilla
1 lb. confectioners sugar
Directions
Melt chocolate and butter together. Blend into mashed potato
with the salt and vanilla. Mix well. Sift sugar. Add a small
amount of sugar to potato mixture, a little at a time, blending
until no sugar is visible. When a spoon is no longer able to
mix, knead in the balance of sugar with well buttered hands.
Turn out on a board and continue to knead until mixture is
smooth, pliable and glossy, buttering hands as necessary. No
crumbs should remain. Press into a buttered 8" square pan.
