I am trying my first sets-o-ribs.
Also, I bought the super secret recipe for rub from our good buddy Jeff, will that work fine with this method?
Personally, I do neither. Un-foiled at a steady temp between 225-250 for 5 hours gets them nice and juicy with a lil' tug.Foil at the very end, throw them in a towel-lined cooler, and allow to rest for 30-45 minutes. Open, slice, and enjoy!
I find that the size of the racks will be a factor in how long you cook them, racks around 2lbs I cook
2-1-1, 2.5 to 2.75 lbs 2-2-1 and the 3 lbs 2.5-2-1. I cook on a Chargriller with A side fire box, with temps in the 230-245 range. YMMV depending on what you are cooking on, the temp you are cooking at and the size of the racks.
I did a little experiment a while back and was most happy with 2-3-1 on that occasion. I've also had mixed results with some of the same methods. It definitely depends on the ribs. I did some meaty, very lean ones yesterday and ended up taking 10 hrs total after having some temp issues.
