Instructions: Preheat oven to 400 degrees. Grease two cookie sheets.

Bring water to a boil in a medium saucepan. Add 1/2 cup butter.

Meanwhile, saute onions in remaining 1/4 cup butter until wilted, about 5 minutes. Set aside.

When butter has melted in water and mixture has returned to a boil, add salt and flour. Reduce heat to low; stir for a few minutes, until mixture makes a ball and pulls away from the sides of the pan.

Remove from heat. Beat in the eggs, 1 at a time, mixing well after each addition. Combine 1 cup cheese with dough. Add onions, mixing thoroughly.

Drop heaping tablespoons of dough onto greased cookie sheet. Brush tops with milk; sprinkle with additional Parmesan cheese.

Bake until golden and puffy, about 35 to 40 minutes.

Yields 24 puffs.
