I buy the Veggie Shreds mozzarella for making mini pizzas. I used the slices for sandwiches and omelettes, and they seem to melt fine. However I cannot get the shredded stuff to melt when I make pizzas. They just turn brown. I recently went to a friend's house and she made pizzas with the same stuff, hers melted wonderfully. I usually cook my pizzas on 400, she did hers on 450. I tried mine again on 450 and it just turned more brown and burnt the crust. Does anyone use this stuff and get it to melt successfully? If so, at what temp?
