1. Pour the flour into a bowl, make a well in the center and break the eggs into it, along with the salt and pepper.
2. Then add the yeast and mix the ingredients using a whisk.
3. Gradually pour in the milk while continuing to whisk until you have a perfectly smooth batter.
4. Cover the batter and let it rest for 1 hour.
5. Meanwhile, prepare the filling for the fritters:
wash and peel the zucchini halfway lengthwise.
Cut off the ends, then slice them into fairly thick rounds.
6. Pat them dry with a clean cloth, and heat the frying oil.
7. Uncover the batter and check that it is pourable.
If not, thin it out with a little cold milk until it is smooth.
Using a slotted spoon, dip the zucchini slices into the batter.
8. Place them in the frying oil.
When the fritters start to turn golden, flip them over so they are golden on all sides.
9. Drain them and then pat them dry with paper towels to remove any excess oil.
10. Keep them warm and repeat the process until all the batter and filling are used up.
