Place the rib racks on a baking sheet. Mix together the salt and paprika, and sprinkle the racks evenly with the mixture. Cover with foil and bake for 2 hours.
Meanwhile, mix together the marmalade and soy sauce.
After 2 hours, uncover the racks and brush them with the marmalade mixture. Raise the oven temperature to 400 degrees F and roast, uncovered, for an additional 30 minutes, basting the racks halfway through with the pan juices.
Cut into individual ribs and serve with lots of napkins.
