On the 4th of July we cooked FIVE Boston Butts - dinner for around 32 patriots. I started 2 on my large in the wee morning hours on my BGE. The next morning my buddy who was supposed to cook two additional butts hadn't started and was out in the boat. I went over to his place to get it started. He has an old Kumado that came with the place. It's an oldie but a goodie. I cleaned it all out per Brant's instructions and loaded up that old dog with new lump. I noticed that the fire box and ring were not tight aginst the egg like our BGEs and that air would/could actually be able to circulate between the egg itself and the firebox and ring. What does this do for venting/circulation etc. I've cooked a steaks, burgers and chicken on it before and the old Kumado heats up good and hot even though the bottom vent only opens about 1/4 of the way. [p]Old sucker works good except for the old style hinge (like a mini) or if you grab the handle you'll touch the outside of the egg.
