Most oven-baked baby back rib recipes are BBQ sauce-based recipes. One recipe from Southern Plate uses the author's homemade Old Number 5 BBQ Sauce, but any BBQ sauce suffices. Another one from Food.com uses Dale's marinade, and another one from Allrecipes.com works with any BBQ sauce.
The recipe from Southern Plate requires you to peel off the white membrane that covers the ribs, using a knife, so that the ribs end up tender after the cooking process and "fall off the back" at chow time. Slather half a bottle of BBQ sauce on the ribs, wrap them in generous amounts of aluminum foil, and bake for two hours at 300 degrees Fahrenheit. Remove from the oven, slather on the remaining half of the BBQ sauce, and bake for another hour with the aluminum foil open this time. The ribs should be ready when the surface is a nice caramel brown.
The Food.com recipe follows pretty much the same procedure, except for the use of Dale's marinade. You also need to bake the ribs longer, about 4 hours at a lower heat of 225 degrees. Glaze with additional BBQ sauce, and bake for another 20 to 30 minutes until the sauce thickens.
The Allrecipes.com recipe requires you to marinate the ribs in BBQ sauce overnight, while inside its aluminum foil wrap and place in the refrigerator. Bake for 1.5 to 2 hours at 300 degrees.
