In a large bowl, whisk all the remaining ingredients together with 4 teaspoons of salt. Uncover the ribs and turn them boney side up. Brush 1 cup of the sauce over the ribs and bake, uncovered, for 30 minutes. Turn the ribs meaty side up and brush with another 1 1/2 cups of the sauce. Bake for about 1 1/2 hours longer, or until very tender; rotate the pans and baste once with about 1/2 cup of the sauce halfway through.
