- In a large pot add the water, butter (diced into cubes) and a pinch of salt. As soon as it starts to boil, remove from the heat and add the flour all at once.
- Place the pot again on low heat and stir vigorously until all the ingredients are combined into a ball. The dough is ready when it leaves a white skin over the bottom of the pan and starts to sizzle.
- Put the batter into the bowl of a stand mixer, and when it is cold, add the eggs one at a time.
- Beat very well between each addition, the dough should be glossy and creamy. Once ready, transfer it into a piping bag.
- Butter very well a baking tray and pipe over it the bignè. Bake at 200 degrees for 15 minutes.
- Once ready, let the bignè cool completely before filling with custard cream or simple whipped cream.
