I cooked Sunday and had the temps around 350. Finished cooking at shut the both top and bottom vents down. It went down to around 250 degrees fairly quick. But 4.5 hours later it was still 200 degrees in the EGG.
I don't have a leaking gasket because I still had a ton of lump left. But I'm curious if this is typical or not. What a great way to keep foiled goodies hot until you need them! Of course when you open it to get them out, that fire can't wait to start again. :S
