First off, my sincere thanks to Villa Roma, essen1, pizzacraver, etc (where in Oz are u pizzacraver? i'm in Melbourne). What you've achieved is incredible.
Avid reader of many many pages on here, and am attempting something a little bit "different". I already have a large Big Green Egg, and am attempting to create the effect of the Little Black Egg within the BGE... thus, the Matryoshka! (yeah, might need to google, i certainly did)
Photos will come later, to give you a better appreciation of how much I suck at the handiwork. Sufficed to say, within the Big Green Egg I have the standard BGE porcelain grate with a 13" pizza stone on top of it. With a fair bit of experimentation, I've ended up with a 18" domed stainless steel colander (yes, a colander), with another 13" pizza stone screwed into the roof of the colander. I'm heading out ASAP to buy yet another pizza stone to use as a buffer (last nights cook resulted in a pizza that caught on fire in under 2 minutes, in addition to nearly killing me - this bitch can get a bit hot). My fuel source is currently mangrove hardwood charcoal, which I'm getting for $AU23 / 20kgs bag, and I'm having a lot of fun lighting it with a MAPP torch (something I may end up using on the top of the pizza if I don't have luck with the 3rd stone).
Over the course of my experimentation, I've managed to get the lovely leopard spots on the base of a pizza but am still struggling to get enough heat onto the top of the pizza. I'm hoping that the 3rd stone (the buffer), will help out by moving the pizza up and closer to the top stone, which I manage to get fairly hot by putting it on before the bottom stones to get some flame directly on it.
I'm seriously hoping that the buffer is all I need to get that 2 minute pizza-heaven. I'm trying to hold off purchasing an IR thermometer, because I also need to buy a Thermapen Instant Read thermometer for everything else I cook on the BGE. I'd rather not drown in expensive add-ons!
Will report back with a photo or 10 and my findings after adding the buffer into the mix!
