Cream Puff Shells

1/2 cup butter or margarine
1 cup boiling water
1 cup sifted all purpose flour
1/4 tsp. salt
4 eggs

Melt butter in boiling water. Add flour and salt all at once; stir vigorously. Cook, stirring constantly, until mixture pulls away from sides of pan and forms a ball that doesn't separate. Remove from heat and cool slightly. Add eggs one at a time, beating vigorously after each until smooth. Drop scant teaspoon onto pan and bake 2 inches apart in 400 degrees oven for 25 minutes.

Stuff shells with tuna or chicken salad.
