I picked up some Swifts St. Louis style ribs packed in cyrovac this weekend and opened the package when I got home. The ribs had a "flavor" about them but didn't appear to smell spoiled. I rinsed them off with water and proceded to prepare two racks to smoke. After they were done(about 5 hours) I took them off the grill and wraped them in foil for about 15 minutes while we got everything else ready for dinner. When eating the ribs, I could still taste the kinda of "brothy" taste to them. What I am wondering is, were these ribs "enhanced"??? or something else??? Looking for others with "enhanced" experience-----
