Al, I would love your bbq sauce recipe. Having a hard time finding one I like. I'd appreciate it!Yes I believe the ribs do absorb some of the juices back into the meat, because when I tried the same method taking the membrane off, the ribs were not as juicy. Both myself & my wife concluded that the only way to smoke ribs is with the membrane still on. Even if you don't foil, the membrane peels right off very easily when the ribs are done. Check out the other rib thread in my signature, those were unfoiled & juicy as can be. https://www.smokingmeatforums.com/threads/naked-ribs-no-rub-no-sauce.263432/. The glossy finish comes from finishing the ribs on a super hot grill with BBQ sauce on them, or maybe it's my BBQ sauce recipe. If you want it, I'll send it to you.
