Take three eggs.
Carefully separate the whites from the yolks.
In the protein you need to add 1 cup of sugar.
Now carefully whisk and gradually gently introduce the flour in parts.
The yolks should be already too, like whipped whites.
We send them to the total mass and mix well again.
Don’t be scared. The dough comes out runny. That’s how it should be.
Pour it into a lined parchment hot mold and put it in the oven for half an hour.
The oven should be hot. Do not open the oven until the biscuit grabs, otherwise it will settle. We check the readiness with a toothpick. It should be dry!
