Exactly. It drives me nuts when people want "fall of the bone" ribs. When the bone is completely void of meat, your ribs are over cooked. Your initial bite will go to the bone, but the rest will stay.
You shouldn't let it upset you. Most people know Med/Rare Beef is tasty and Juicy but there are still a lot of folks that insist on Well Done Steaks! Are they Wrong? Dad spent 50 years trying to convince Mom that Well Done destoyed the flavor and texture of Beef...
Many folks that expect Fall of the Bone Ribs, just think that is the way they are supposed to be. It is the National Chain Restaurant's fault, among others. A place like Chili's or Outback and others, have the Ribs cooked, some Steam Smoked, wrapped and refrigerated. When an order comes in, the already very well done Ribs hit the Grill, Broiler or very hot Oven to be reheated and sauced to death. Additionally, a large percentage of well known Northern and Southern BBQ Places, do such high volume of Ribs, that they have no choice but to Smoke, Foil and Hold their ribs at 150°F. The Collagen connective tissue continues to breakdown as long as the ribs are held hot. There is no way, with those styles of Moist cooking or long term holding, you can expect or even get Competition Bite Through Ribs.
Many years ago, I and a group of Chef's, judged a huge Rib Cookoff in Central PA. This annual event had several local Teams, attracted some Pitmasters from all over the country and had some area Chain restaurants participate as well. The Judges Choice was a guy that smoked up some great, bite through, Memphis Style Dry Ribs...The Peoples Choice award went to a National Chain Restaurant...
I just saw an episode of Man, Fire, Food, where a popular southern Q joint was making BIG $$$ with their Famous, Secret Recipe, " Boneless " Racks of Ribs...You could see that the slabs of Baby Back Ribs were just cooked to the point that the bones could be pulled out. The host used a knife so cut the meat up but the meat was so fall apart that a fork was all that was needed...JJ
