Moravian Sugar Cake

Dissolve yeast in warm water.

To hot mashed potatoes, add 1 cup sugar, 4 tablespoons margarine, 1/2 cup shortening and salt. Add yeast mixture; mix well and let stand in warm place until "spongy."

Add eggs and sufficient flour to make soft dough.

Allow to rise (covered) at least 5 hours in a warm place.

Punch down and turn onto a surface; knead lightly 3 to 4 times.

Spread out evenly in greased biscuit pan.

Let rise for 1/2 hour or doubled.

Punch holes about 2 inches apart; place brown sugar mixture (about 1 teaspoon) and piece of butter into each hole.

Bake in 350° oven for 20 minutes.
