4-Return to heat briefly to dry the dough slightly; then transfer to a mixing bowl to cool.

5-Incorporate eggs one at a time, beating thoroughly after each addition to ensure proper emulsification.

6-Pipe the dough onto prepared sheet in desired shapes; maintain spacing for expansion.

7-Bake in a preheated oven at 200°C (400°F) for 10 minutes, then reduce to 180°C (350°F) and bake for another 20-25 minutes until golden and puffed.
