Common Mistakes to Avoid

Boldly rush the mixing process: Overmixing the meat can result in tough meatballs. Mix just until combined for tender results.
Boldly disregard cheese varieties: Using only one type of cheese might limit flavor depth. Mixing mozzarella and Gruyere enhances taste and texture.
