With milk, yes. They burn if you forget the milk.

A rather late reply to this. Does that warm up in the oven before placing the pizza on it? Does it cook them nicerer?

 

Someone on Dragon's Den a little while ago invented a magic pizza cookerer. Well, a metallic dome that you heat in the oven and place the pizza on to cook. Supposed to stop frozen pizzas being soggy in the middle.

I'm afraid it's a late reply back, sorry!

 

The pizza stone needs to warm up in the oven for a good chunk of time before the pizza goes in onto it. Totally worth using 3 times the amount of electricity though for the end result.
