Preheat oven to 350 degrees. Arrange ribs in single layer on baking sheets, season both sides with Hickory smoked sea salt and pepper, cover tightly with foil. Bake until very tender, about 1 hour 10 minutes.
To obtain ribs with meat on both sides, cut out every other bone. (Can be prepared 2 days ahead. Cover tightly with foil and refrigerate.)
Arrange ribs in single layer on baking sheets, coat generously with BBQ sauce. Bake until ribs are hot and sauce starts to glaze, about 25 minutes. Line platter with a hardy lettuce or kale and top with ribs. Serve hot.
Combine all ingredients in a heavy medium saucepan. Bring mixture to boil, stirring frequently. Reduce heat, cover partially and simmer for about an hour. Sauce can be prepared up to 1 week ahead; cover tightly and refrigerate.
