Prepare the Dough: In a saucepan, combine water, butter, sugar, and a pinch of salt. Heat until the butter melts and the mixture begins to boil.
Incorporate Flour: Remove from heat and add all-purpose flour at once, stirring vigorously until the dough forms a smooth ball and pulls away from the pan.
Cool and Add Eggs: Let the dough cool slightly. Add eggs one at a time, mixing thoroughly after each addition until smooth and glossy.
Pipe the Dough: Transfer the dough to a piping bag and pipe into desired shapes on a lined baking tray.
Bake: Bake in a preheated oven at 200°C (390°F) for 20–25 minutes, then reduce to 180°C (355°F) for another 10–15 minutes until golden and puffed. Avoid opening the oven during baking.
Cool: Remove from oven and let cool completely before filling or glazing.
