Put the ribs in a very large soup pot or kettle. Add the salt and enough water to cover them. Bring to a boil and let boil for 30 minutes. Remove from the heat and drain.
Whisk the remaining ingredients together in a medium-size mixing bowl, blending well. Put the ribs in a large, deep braising pan or roasting pan and pour half of the marinade over them. Cover and refrigerate for 2 to 3 hours, turning the ribs in the marinade every hour.
Preheat the oven to 350 degrees F.
Cover with foil and cook, basting with the reserved marinade and turning the ribs every 15 minutes, for 1 to 1 1/2 hours.
Remove the ribs from the pan. Divide among 6 plates and garnish with sliced scallions.
