This is a riot! So I have purchased my 4.5 lb butt. I thought I'd glance through prior posts related to duration of cook. Some people like 2 hours per lb as a rule of thumb. With that, I'd probably wait until tomorrow morning and start it early. I was thinking butt on at 8, ready to pull from fire around 5, wrapped for a couple hours and we'd eat around 7. [p]Some posts say that even the wimpy little butts go 16 or 18 hours.[p]That would be bad news if I start at 8 a.m.[p]Should I put it in late tonight and just keep it warm or reheat it or is 8 tomorrow morning a pretty sound approach.[p]Thanks all--I swear this is the last topic for me! I'll probable turn this poor little computer off for the next three days.
