Sweet or Savory (puff pastry dough)
From "Martha's Recipes"
Line two cookie sheets with parchment paper and set aside.
In a medium saucepan over medium-high heat, combine butter, sugar, salt, and 1-cup water. Bring to a boil and immediately remove from heat. Using a wooden spoon, quickly stir in the flour until combine.
Return pan to medium high heat and cook, stirring vigorously, until mixture pulls away from the sides and a film forms on the bottom of the pan, about 3 minutes.
Remove from heat and transfer contents to a bowl to cool slightly, about 3 minutes. At this point, you can use a wooden spoon to stir in eggs or use an electric mixer with dough hooks attached. Either way mix in eggs, one at a time and stir vigorously, until each egg is entirely incorporated. Use dough immediately.
Bake, rotating sheet halfway thought, until puffs are golden, about 20 to 25 minutes. Cool
