WARNING: Stone is not pizza. DO NOT BITE.
Pizza stones aren't some amazing natural phenomenon. You can't bite into this stone and find it tastes like pizza. What you CAN do is put a pizza on it and slide it into the oven. If you try that, you'll find your pizza is now maybe better-tasting than it was before, when you didn't use a stone. It's sort of a way to make your pizza into a better pizza. You can play some montage music while it cooks if you like.
