Elise many places sell "Rib Tips" or Small Ends or even half a rack of ribs as Small or Large Half. Around here you buy them by the pound, usually soaked in sauce. We like ’em!
We used to buy Rib Tips at Stater Brothers.. a 10 lb box of "Danish Ribs" (Raw). They were the first 2 or 3 bones on the short end of the rack.
