Tried spare ribs from Costco this weekend. Watched the videos, read the articles, but I'll be ****ed if I could find the membrane on those spare ribs. Anyone have experience with spare ribs from Costco recently - the cryopack version? One article I read indicated they might take the membrane off already, but the post was old and may have been referring to baby backs. I had to trim the tips and skirt off, so I kind of doubt they could take off the membrane and leave that stuff on... Maybe I'm just a dunce at identifying and removing the membrane.
