Re: Oven done BBQ Ribs ... drop dead good.
Recipe sounds delicious....but let me offer a variation on the theme...
I start with a barbecue rub concocted from chili powder, cayenne, paprika, brown sugar, cumin, and garlic powder and anything else that catches my eye. Hundreds of recipes for rubs online..pick one and modify to taste.
cover the ribs liberally with the rub and then let them set a while.
I oven roast mine at a lower temp (275) and longer (2.5 to 3 hours) until meat just begins to separate from the bone. At this point you can wrap them up and keep them in the fridge for several days if you like.
If you've had them in the fridge, return them, wrapped in foil to the oven for 20 or 30 minutes just so they get hot and don't need to stay on the coals for a long time.
Place them over slow coals... charcoal or wood works best but a gas grill will do if you have no choice. The fat from the ribs should generate a lot of smoke. Cover the grill but open and turn a couple of time so the ribs don't burn and get tough.
I've found putting the sauce on while the ribs are over coals, results in a lot of carmelized sugar but some folks like this...if so, go for it. Or, remove the ribs after smoking a while, transfer to a pan you can cover tightly, then slather on the sauce, cover, and let them set a while.... They'll be plenty saucy!
I generally don't make my own sauce unless the cupboard is bare. Sweet Baby Ray's Sweet and Spicy sauce with a generous addition of Cholula Hot Sauce is pretty good.
