Choux Pastry:
Method of Preparation:
In a pan, bring the water, milk, butter, salt and sugar to a boil;
As soon as it starts to boil, pour in the flour and mix quickly to avoid lumps; cook the dough until it no longer sticks to the bottom of the pan and is very dry;
Place the dough in the bowl of a stand mixer fitted with the paddle and beat until all the steam comes out; add the eggs in 3 additions and finally the hot milk, if necessary (to adjust the correct texture of the dough);
Pour the dough with a medium round nozzle onto silicone paper or Teflon sheet (balls measuring approximately 3cm) and place a disc of crunchy açaí on each one;
Bake in a preheated oven at 180°C until golden and stabilized; lower the oven to 160°C and bake until very dry;
Remove from the pan and let cool on a wire rack; fill with a pastry bag and sprinkle with icing sugar before serving.
