Prepare the Cheese:

1. Cut each mozzarella string cheese stick into bite-sized pieces and set aside.

Set Up the Breading Station:

1. In a medium bowl, whisk together the eggs and milk until well combined.
2. Prepare two additional bowls: one with flour and the other with Italian bread crumbs.
3. If you want to add a little heat, mix a pinch of cayenne pepper into the flour or bread crumbs.

Bread the Cheese Bites:

1. Dip each piece of cheese into the flour, then into the egg mixture, and finally into the bread crumbs. Make sure each piece is fully coated.
2. Place the coated cheese bites on a plate as you finish breading them.

Heat the Oil:

1. In a medium-sized skillet, heat about 2 inches of vegetable oil to 350°F (175°C).
2. Test the oil by placing the handle of a wooden spoon into the oil. If bubbles form around it, the oil is ready.

Fry the Cheese Bites:

1. Fry 5-7 pieces at a time for about 30 seconds, or until golden brown. Be sure to keep them separated to prevent sticking.
2. Use a slotted spoon to remove the fried cheese bites and place them on a plate lined with paper towels to absorb excess oil.

Serve:

1. Serve immediately with your favorite dipping sauce, like marinara, or enjoy them on their own!
