Preheat oven to 325 degrees. In a bowl combine all ingredients except ribs to make a sauce; season with salt and pepper. On a rack set in a roasting pan season ribs with salt and pepper and brush with a thick layer of sauce. Roast ribs, basting every 30 minutes, until tender and falling off the bone, about 1 1/2 hours. Slice into individual ribs before serving with potato salad.
In a bowl, stir together mayonnaise with cilantro, garlic, salt and 7 turns black pepper. Add potatoes and onions and toss to combine thoroughly; cover and refrigerate up to 24 hours before serving.
