"Extra cheese" refers to the addition of more cheese than the standard amount on a dish, commonly used in pizza and pasta. This option enhances the flavor and texture, making the dish richer and creamier. It is popular among cheese lovers who enjoy a more indulgent experience. When ordering a pizza, for example, customers can request extra cheese for an additional charge. This customization allows individuals to tailor their meals to their preferences, often resulting in a more satisfying and flavorful dining experience. Many types of cheese, such as mozzarella or cheddar, can be used for this purpose.
