I saw that episode. I don't remember seeing raw meat, but it has been a while. I wonder if the ribs were boiled (please forgive me for using the "b" word). They looked amazing either way. I grill-foil-grill babyback ribs on my OTS in the winter. They really do taste amazing.
If you baste and flip a lot, there is no reason you can't make a very tender rib....even without foiling or boiling.
