Place the ribs to a large glass or ceramic baking dish and pour 2 cups of Coca-Cola or Dr. Pepper over them. Reserve the third cup of the soda for a sauce to be made later. Cover the pan securely with plastic wrap and let the ribs marinate in the fridge overnight.
Pour the remaining 1 cup of soda into a blender or food processor and add the ketchup, brown sugar, chili powder, pepper, dry mustard, and cinnamon. Blend until smooth.
Take the ribs out of the pan they have been marinating in and toss that soda. Put the ribs in a roasting pan that has been coated with cooking spray, brush liberally with part of the sauce, cover the pan with a lid or foil and roast in a 225 F oven for about 2 1/2 hours or until very tender. A paring knife should go in easily, and/or you can measure them for doneness with a cooking thermometer – they should be around 200 degrees.
To finish, grill the ribs over medium-high heat, basting with some of the leftover sauce until the outside is crispy, about 10-15 minutes. While the ribs are cooking, simmer the remaining sauce on the stove over medium-low heat for about 15 minutes until a little thick.
You can either cut the ribs into one rib pieces or serve them up in sections. Enjoy!
Notes
Ribs: We always use baby back pork ribs for this recipe. They are the right size and contain the right amount of lean vs fat ratio, and (bonus points!) they are very affordable.
Soda: You can use any dark soda from Coke to Dr. Pepper to your friendly neighborhood store brand…just make sure it is the regular variety and not the diet version. You need the sugar as well as the carbonation in the soda to tenderize your ribs.
