You can pretty much treat them like any other rib. If you have never dealt with a beef back rib membrane, you are in for a treat...I swear there are 2, but I cant get the 2nd one off, so I just score them. Those are extremely fingered, which for that price, I would expect. As they cook, they are really gonna pull back. I would try 275° membrane down. At the end of that time, try one, if they are not tender enough, 45 minutes in foil should finish them
