1 small potato, peeled, cooked, and mashed
1 cup grated Muenster cheese
2 tablespoons butter
1 cup flour
1/2 teaspoon salt
1/2 teaspoon baking powder
Dash cayenne to taste (optional)
1/4 cup milk or 1 beaten egg yolk

Preheat oven to 375 degrees. Combine potato with cheese and butter. Sift dry ingredients together and add to potato mixture, mixing well. Turn onto lightly floured board. Knead dough three or four times and roll out to 1/3-inch thickness. Cut with round cutter and place on ungreased cookie sheet. Brush tops with milk or egg yolk and bake 10 to 15 minutes, or until lightly browned. Yields 10 to 12 biscuits.
