Baby back ribs come from the parts of the ribs that are connected to the backbone, beneath the loin muscle and have around half an inch of loin meat attached to the top. Baby back ribs are more tender and leaner than spare ribs, and are typically more expensive. Each rack is around 2 pounds, around half of which is bone, and one rack feeds around one hungry adult.
BBQ aficionados vary on how to make the best fall off the bone, finger licking good ribs. I have used different methods myself from the oven to the smoker but the main thing is to cook them low and slow. Time is always the winning ingredient. Here is a link to a recipe I use when cooking ribs on a ceramic grill.
