If you'd have asked me even a day ago I'd have told you not to foil, just no need! Well, never say never! My wife crockpotted a slab of baby backs a few weeks ago, I just couldn't get them done right then, I have health issues with great days and really bad days! To say they were tender is an understatement! And pretty darn good! All I heard after that "Why can't you cook ribs that fall off the bone like that?" Grrrrrr! So today was my dads B-day and he asked me to do some smoking and invite some people over. I did "winglets" and three slabs of ribs. Two slabs I just did like normal, the third I planned to do the 2-2-1 method. Not exactly sure what happened, it was 92deg 46% humidity today and I averaged a cook temp of 208deg. Two hours I pulled one slab and foiled them, two more I pulled them, unfoiled and went to grab them with the tongs, they just fell apart! The other two had an IT of 150's, so I wasn't sweating temps. But man! It was night and day between the different cooks! I'm sold, more tender, more juice and I couldn't even cut them because they were so soft! I have to concede defeat, I guess I'm a foil guy now.
