Preheat oven to 375F. Grease a baking sheet; set aside. For pastry, in a medium saucepan, combine the water, milk, butter, salt, and nutmeg. Bring to boiling. Add flour all at once, stirring vigorously. Cook and stir until mixture forms a ball. Remove from heat. Cool for 5 minutes. Add two of the eggs, one at a time, beating well with a wooden spoon after each addition until smooth. Spoon batter into a pastry bag fitted with a round tip with a 1/2-inch opening.
