To make Smoking Mixture: In medium bowl, combine all ingredients.
To make Spareribs: Cut ribs into 2 to 3 bone pieces and place in hotel pan. In large bowl, whisk together remaining ingredients. Toss 3 1/2 cups with spareribs (reserve remaining marinade for basting); refrigerate 2 to 12 hours.
Line 2-inch-deep hotel pan with aluminum foil; spread smoking mixture evenly across the bottom. Place rack in hotel pan. Drain ribs from marinade and place meat side up on rack over smoking mixture; cover hotel pan tightly with foil. Smoke in 350°F oven for 30 minutes. Uncover, baste ribs with reserved marinade and roast for 40 minutes. Baste ribs again and roast 5 minutes longer or until tender.
