Cream Puffs

1/2 cup butter or margarine
1 cup water
1 cup all purpose flour
1/4 teaspoon salt
4 eggs

Preheat oven to 400 degrees. In a medium saucepan, melt butter. Add water, bring to a boil. Add flour and salt all at once; stir vigorously. Cook and stir until mixture forms a ball that doesn't separate. Remove from heat; cool slightly, about 5 minutes. Add eggs, one at a time, beating with a wooden spoon after each addition (1 to 2 minutes, or until smooth). Drop batter by heaping tablespoons, 3 inches apart, onto a greased baking sheet. Bake in a 400 degree oven for about 30 minutes or until golden brown and puffy. Remove from oven; split, removing any soft dough inside. Cool on a wire rack. Fill with whipped cream, pudding, ice cream, or fruit mixture.
