The day before cooking: Cut ribs into portion size, Salt
and pepper. Place in deep pan, big enough to hold ribs and sauce. Mix soy sauce, marmalade, plum jam, garlic and ginger. Pour over ribs. Cover with foil (airtight).
Put in refrigerator overnight. Next day, stir and mix the sauce and ribs well. Cover with foil (again, airtight). Cook in the pan on the grill for 3/4 hour or until tender. Take out, put on grill rack and brown.
Takes only a few minutes.
