Ribs are undoubtedly a cornerstone of American summer barbecues, especially in the South where it's practically an art form. Die-hard 'cue masters will argue there's a difference between barbecue and grilling. And there is: Barbecue is a low and slow process of cooking meat in a smoky humid environment.
Grilling is about quick contact-cooking. Steaks and burgers are grilling. Ribs and pork shoulder are barbecue. Barbecue can be broken down further into wet and dry versions. It's pretty self-explanatory but the debate as to which is better is one that will never be decided upon. The secret is in the sauce—or is it the rub?
What most Americans know as barbecue is based on the wet barbecue technique that originated in Kansas City. Large food brands further popularized wet barbecue with their lines of sauces. Wet barbecue is all about the sauce whereas dry barbecue is all about the rub. No thick sauce is used to baste the meat except for a mop sauce (typically made with vinegar, which helps keep the meat moist). You'll find dry barbecue in Memphis, where they serve sauce on the side for dipping, but you will never see it slathered on the meat. Most at-home barbecue includes a combination of both dry and wet methods.
