Mozzarella sticks in batter are a delicious appetizer made by coating sticks of mozzarella cheese with a flavorful batter. The batter is typically a mixture of flour, eggs, and seasonings that provide a crispy and golden exterior when deep-fried. The result is a mouthwatering combination of gooey, melted mozzarella cheese inside and a crunchy outer layer. These cheesy treats are often served with marinara sauce or other dipping sauces, making them a popular and satisfying choice.
