w+a's comment on the "wine and pizza" thread about 4 cheeses on his pizza got me wondering... what kind of cheeses do you like to use to make your own pizza? in what combinations?
i use mozzarella a lot, and ricotta pretty regularly (often in tandem), but i'm wondering what else people have used, and in what combinations?
mozz and fontina maybe? asiago and ricotta?
i'm especially curious as to which combinations you use when you're trying to avoid tomato sauce on the pie...
