2/3 cup water
1/4 cup butter, cut into small cubes
1 teaspoon white sugar (Optional)
1 pinch salt
1/2 cup all-purpose flour
2 large eggs, lightly beaten
Combine water, butter, sugar, and salt in a medium saucepan over medium heat; cook until butter has melted and mixture comes to a boil.
Add flour all at once; stir vigorously with a wooden spoon over medium-low heat until mixture forms a ball and the saucepan is coated in a light film of flour, about 2 to 3 minutes.
Remove the pan from heat and let cool for 10 minutes.
Beat in eggs, one at a time, with the wooden spoon until the mixture forms a sticky dough with a pipeable consistency.
