Pat the ribs dry with paper towels. Sprinkle with salt and pepper all over. Put in a baking dish. Cut the baby potatoes in half, cut the onions and carrots into strips. Place vegetables in a baking dish. Pour in water or both into the bottom.
Pour 1/4 c. of your sauce over the top of the meat so it's coated. Cover the baking dish with a lid or foil in 2 layers. Put in preheated oven, at 350 F.
Bake for 1 hour and 30 minutes to 2 hours or until a bone easily lifts out of the meat when you gently pull it out. To caramelize sauce on to the top, remove foil, pour another 1/4 cup over the top and set to broil for a few minutes until bubbly and browned.
Serve with veggies on the side and drizzle remaining sauce over the top of each serving.
