I am watching this special on Food Network with Paula Dean hitting the South and tasting BBQ. She is at Memphis in May and this dude on the Mile High team is saying that you know the baby back rack is done when it folds on itself (which I agree with) but he mentions that the membrane is dissolved by the cooking process and thats when you know it is done. I have never heard this. I have heard nothing but bad things about the membrane and that it should be destroyed at all costs! Anyone got any insight?
