Was it the backstrap or tenderloin that was left attached? I think typical "rack of x" uses the tenderloin. Heck, now I'm not so sure.
I think there's some crossover in what's considered tenderloin and backstrap. I know for a fact that what I saw on that program was the backstrap as it connected an entire rack of ribs. No way was that the inner loin or what I typically refer and hear referred to as the tenderloin.
Whatever it was, it looked GOOD......
