Wow, after almost 20 years of cooking pizza on a Big Green Egg I learned something amazing tonight.
In all my years of cooking pizza on the egg I've struggled to get the top cooked correctly. It generally consisted of a crap-ton of charcoal in the cooker to get the temps up and the ensuing struggle to balance getting the top cooked without the bottom burning. This also meant I was limited to about 4 pizza's before the charcoal ran out. Tonight I got the pizza stone up to about 450* since my daughter prefers hers lighter, but in an effort to extend the cook time I added a couple of small pieces of hickory to the coals. The flames immediately shot the dome temp up to about 650* which put the perfect char on the top of the pizza without raising the temp of the pizza stone.
10 out of 10, highly recommend
This is my pizza which I prefer with some black spots to it.
