Is 2 days too long to keep wrapped in plastic wrap marinating with the the rub?
Never forget the store/oven can save a great smoke if you had lost power after starting the smoke. If you get a few hours of good smoke the oven is as good or better than the pit.
Oh and I might consider re-rubbing them before smoking. You can't get too much of a good rub IMHO That bark is the cooks share .....LOL
No you are not ruined. You will just have a lighter smoke flavor. Looks good so far!!
As for sitting with the rub for 2 days, you are good. I don't see any issue with that. I would do the same as said and apply a bit more rub just before going into the smoker.
Just from looking at your picture. I would make a tent to go over your AMNPS, you may have gotten some drippage and killed your burn path. I use one on both the AMNPS and AMNTS. Don't run into issues of it going out nearly as much.
Yeah, I would put a drip cover over your AMNPS--I just use a tin foil pan cut to size. By the looks of your AMNPS, one entire row burned, so you probably got 3 to 4 hours of smoke before it went out.
Great looking smoke IMHO...... You can lay on too much smoke but other than that, its really hard to mess one up. Looking at yours, I am pretty sure its a winner.
Believe me I am wanting a bun after looking at that picture!
Great smoke. Now are you going to repeat it all next time to get another great result??
