Spudnuts

1 cup mashed potatoes (in a pinch, I've been known to use prepared potato pearls)
4 tablespoons shortening
1 1/2 tablespoons salt
2 eggs, beaten slightly
2 cups scalded milk
1 1/2 cups sugar
8 cups flour (you might need 10 - just start slow and add until dough is manageable)
3 1/2 tablespoons yeast dissolved in 1 cup hot water and 1/2 tablespoon sugar

Mash potatoes with milk until creamy. Cream together shortening, sugar and salt. Add to potatoes. Add all other ingredients, knead for 5 minutes and let raise until double (about 1-1 1/2 hours). Roll out and cut into donut shape. Let raise 30 minutes. Fry in hot oil at about 350.

Drain on paper towels then dip in glaze.

Glaze:
1/3 cup melted margarine
2 cups powdered sugar
1 1/2 teaspoons vanilla
4 to 6 tablespoons hot water
