For one batch, you'll need:
+ 1 cup of water (filtered, if not from a well)
+ butter, 6 tablespoons
+ salt, 1 pinch
+ sugar, 3 teaspoons (omit in savory variations)
+ eggs, 4
+ flour, 1 cup
Heat first 4 ingredients in a small saucepan, until butter is completely melted and water simmering. Remove from heat. Add the flour (all at once), and stir rapidly to combine. Replace on heat source, and stir until the mixture pulls away from the pan and forms a dough ball. Remove from heat.
Using an electric mixer, incorporate the eggs, one at a time.
