Mozzarella di Bufala is a delightful Italian cheese made from the milk of water buffalo. It’s too fragile for baking, but it’s an exquisite addition to salads, especially fresh tomatoes and basil. It also melts perfectly on top of a hot pizza right out of the oven. If you can’t find bufala, you can spread grated fresh mozzarella under the tomatoes before you bake your pizza. Or sprinkle it with grated Parmesan, also, before you bake it.
