The Cadillac Cut is a technique for cutting ribs. It is also known as the Hollywood Cut.
Instead of cutting the ribs by slicing the middle of the meat between the bones the meat is cut all the way to the adjacent bone on either side.
The result is a rib with a lot of meat on each side of the bone.
Using the Cadillac Cut technique will result in fewer ribs per rack because every other bone will have all its meat cut off.
The Cadillac Cut is used by some teams in BBQ competitions to provide ribs that look really meaty.
