Thank you guys for the good replies so far.
@John Setzler I did learned to cook pizza on the BG with your "Kamado Joe - Pizza 101" video where you go to 925 F before inserting your pie. I understand you will lose heat when opening the done, and indeed, the pizza will be ready within 90s. In any case, I am very pleased with the results so far.
After your comments, I am a bit worried to try that again.
Are you concerned about components of the BG suffering at those high temperatures? Any specifics?
