Heat oven to 400ºF. In 2 1/2-quart saucepan, heat water and butter to rolling boil. Stir in flour; reduce heat to low. Stir vigorously over low heat about 1 minute or until mixture forms a ball (warning: your arm WILL get tired); remove from heat.

Beat in eggs, all at once; continue beating until smooth. On ungreased cookie sheet or Silpat lined, drop dough by slightly less than 1/4 cupfuls about 3 inches apart. Bake 35 to 40 minutes or until puffed and golden. Cool away from draft, about 30 minutes.
