Well I don't have my outdoor kitchen done yet but did a trial fit of the egg and figured I would fire it up why I was at it. First cook was burgers. Used RO lump and the burgers had a funny taste from the charcoal. So today I decide to cook a couple steaks but this time the plan was to get it real hot to burn that crappy smell / taste out. It was like someone put out a camp fire taste/smell. Same smell u get by sniffing the bad. I am new to lump and like wicked a lot better for this reason. Anyhow, I get the BGE really hot (off the scale) - didn't take long. I opened the lid to clean the grate and whooosh. A huge fireball came out and scared the crap out of me. Burned my hair on my arm. Eye brows , eye lashes and hair on one side. It was right out of the movie backdraft. Now I read about. Burping the grill. So at what temp do u have to burp it?? I had no idea. Good thing I didn't get burned. Now I look for a fireball everytime I open the lid.
