The iron cast pizza pan is used to cook all types of food. However, you have to be careful when preparing food with high acidic content. Before you do so, make sure that the pan is well seasoned. If the layers of the seasoning are not thick, the acidity of the food will burn through and discolor the pizza pan. In the end, the food will also have a hint of a metallic taste.
If you wish to cook acidic food such as beans on the cast iron pan, you should continuously season your pan. That way you will prevent the corrosion and the strange taste in your dish. Remember to season your pizza pan to increase its versatility constantly.
