Thanks, Todd, I'll read that post you linked.
I had the platesetter with legs down, then the three little bge feet, then the bge pizza stone. I lit the egg, opened everything up, and walked away. When I came back the needle was all the way around and the top was sealed.
I pulled on it just a bit and it popped open.
I dialed things back a bit, waited, and when I came back, it was down to about 625. I managed to get it back up closer to 700 for the first pizza but the second pizza, I couldn't get it above about 640.
I had completely cleaned out the firebox and raked all the ashes out. So my problem was I probably didn't start with enough lump to withstand the extreme high heat it blasted away at. But boy, is the inside of that egg clean now!
I have had fairly good luck with pizzas on the egg in the past. Now I'm looking to perfect some crust recipes for different temp cooks and pizza styles. I always try new recipes and never kept track of what I did, so never could remember which ones turned out better than others. Now I'm keeping track and making notes.
