In a floured surface, knead for a couple of minutes, till the dough looks smooth. Let the dough rest for 10 minutes.
Roll the dough, fold it in 3 and let it rest for another 10 minutes. Repeat this process another 2 or 3 times.

Bake in a preheated fan forced oven at 190°C for 12-15 minutes, depending on the size you choose to make them.
They have to become golden. Serve at room temperature.
