The primary difference here from my perspective is radiant heat vs. indirect
heat. Actually I had expected you to make a correction, but about the fact
that IIRC you do indeed use a burn down pit.
I learned some things about big offsets when I cooked on a Horizon at the
Lenexa contest (won 15th pork and 7th brisket, around 150 teams). Not my
usual team but cooking with a buddy who just bought the Horizon and had no
idea how to use it. But I had a great coach come help me out. Her being nice
to look at with a liquor store sponsored pit party was a nice bonus. ;-)
Anyway... the big offsets, except for the reverse flows, can create some
amount of radiant heat exposure, depending on meat placement in the pit. So
I can start some pork or brisket near the fire box and they will develop a
certain amount of char (this is a very good thing). But to control that and
slow down the later stages of cooking, I would move the meat back away from
the firebox, and eventually wrap. Not a lot different from letting a direct
fire gradually reduce. I could get anywhere from 275F or so near the
firebox, lower on the lower level, to a nice cycling 210-225F on the cool
end of the pit. (bragging that I had that temp stable and predictable all
night after a couple hours of learning curve, but had to get up every two
hours to feed that hog) My old NBBD was just too small to offer all these
coooking zones so it was an education for me.
So what is it that I was doing? BBQ, barbecue, smoking, or grilling? I used
radiant heat and indirect heat.
I could also reference some ancient tribal cooking methods which effectively
utilized offset heat and smoke for cookiing. No steel pit, more like piles
of molded clay. What were they doing?
Not sure it behooves us to split hairs, but by the same token, it does
behoove all of us to uphold our own folk cooking traditions centered around
low and slow wood fired methods, to preserve and pass on to the next
generation. And it also behooves us to support others in their efforts to
preserve their own traditions, even when they differ from our own.
