Working from home certainly does have some perks. I never could've done this on a work day before COVID. Got a 3 pack of baby backs from Costco a while back and took 'em out of the freezer yesterday. I was thrilled to see all three already had the membrane removed. I rubbed two down with a modified BRITU rub (mixed with some leftover small amounts of Stubb's BBQ rub and Chris Lily 'Championship' rub. The third was just given some Chinese 5 Spice. I cooked that one until just shy of done and took it off to cool. I then vac sealed it and will reheat on the Performer at a later date with an Asian inspired sauce, some sesame noodles and probably an Asian slaw. The other two got some fresh No. 5 Sauce and the kids and I devoured about a rack and a half, along with some Caesar salad. Good cook overall - I ran temps around 275 and they took about 3 hours. Two large chunks of apple and one small chunk of cherry. K-Pro for fuel. To fit all 3 on the top rack, I 'rounded' them. I think I like this method, as the short, skinny ribs on the ends get a little protection. The drawback is you should probably flip them halfway through, as the top of the racks seemed to cook a little faster than the bottom.
