Make a classic dough with yeast, like the one for homemade bread:
- put dry yeast, one tablespoon of sugar and one glass of flour in warm water, let sit for 10 minutes;
- then, add 2-3 tablespoons of oil, 0.5 teaspoon of salt, the remaing flour and knead into a smooth and non-sticky dough, even rather hard;
- leave it for 30-60 minutes to rest and rise.
