Step 1

Preheat the oven to 400°. Line 2 baking sheets with parchment paper. In a medium saucepan, combine the water, milk, butter and salt and bring to a boil. Add the flour and stir it in with a wooden spoon until a smooth dough forms; stir over low heat until it dries out and pulls away from the pan, about 2 minutes.

Step 2

Scrape the dough into a bowl; let cool for 1 minute. Beat the eggs into the dough, 1 at a time, beating thoroughly between each one. Add the cheese and a pinch each of pepper and nutmeg.

Step 3

Transfer the dough to a pastry bag fitted with a 1/2-inch round tip and pipe tablespoon-size mounds onto the baking sheets, 2 inches apart. Sprinkle with cheese and bake for 22 minutes, or until puffed and golden brown. Serve hot, or let cool and refrigerate or freeze. Reheat in a 350° oven until piping hot.
