1. Set up 3 shallow bowls or plates. In the first one, put the flour. In the second one, place the breadcrumbs. In the last one, beat the eggs.

2. In a small saucepan, heat the oil to about 360 degrees F (180 degrees C).
3. Dip each mozzarella cube in the flour first and shake off excess. Then dip it in the beaten eggs, then the breadcrumbs (you can repeat dipping in the eggs and breadcrumbs).
4. Working in batches of 3 (or more, if you use a bigger saucepan), lower cubes into oil and fry until light golden brown, about 30 seconds per batch.

5. Transfer to paper towel to drain. Serve immediately.
