I got a Pizza stone for my BBQ, it is dead simple to use :
- Have a hooded BBQ heat it up tp 220 dec C with the pizza stone in side
- Make your favourite pizza
- Place it in the BBQ for 10 minutes
- While it is cooking down a cold beer :D
- Eat pizza and have another cold beer :D
Life doesn't get any better (and the pizza is better than the commercial ones)
