Not on purpose or for any particular reason, but did this in my drum this afternoon.
Started the drum at 250*
Put the ribs on and ran them at 250* for an hour
Then 275* for an hour
Then 300* for just under two hours
I had no plan for this, was suppose to have some guests coming over, ended up running some errands later instead, which is the cause of the changing temperatures. Had nothing to do with the ribs themselves, other than wanting them to get done before we left. Like they say, even a blind squirrel finds an acorn every now and then.
Easily my best rack yet. Great smoke ring (I"m guess from the "low" starting point) and lots of pig honey at the end (can't really see it, these pics are an hour and a half off the smoker)
