     1/4  cup           packed brown sugar
   2      tablespoons   dark oriental sesame oil
   3      tablespoons   apple cider vinegar
     1/3  cup           freshly squeezed orange
                        - juice
   1      teaspoon      ground ginger
   2      teaspoons     dry mustard
   2                    green onions -- white part
                        - only -- chopped

                        - to 2 inches

Preparation:

Combine the hoisin sauce, soy sauce, brown sugar, sesame oil, vinegar, orange juice, ginger, mustard, and green onions. Marinate the ham in the sauce several hours at room temperature or overnight, if possible, in an airtight container in the refrigerator. (I like a plastic bag.) Preheat the grill. Drain the steak, saving the marinade, and grill, 2 to 3 inches from the heat, 5 to 8 minutes on each side, or until heated through and lightly scored with brown from the grill. Meanwhile, heat the marinade until boiling. Serve over the ham.
