Question: do parmesan and mozzarella go together?
Answer: No, you should not substitute mozzarella cheese with parmesan on a pizza. Parmesan cheese is way too hard, pungent and salty for pizza. Personally, I don't even want a smidgen sprinkled on my pizza after it is baked — for my taste buds, the sharp aroma and taste of parmesan ruins the taste of the pizza.
