1 pound fresh sea scallops or shrimp, peeled and deveined
1 large mango, peeled and cut into wedges
1/2 papaya, peeled and cut into wedges
1 large red pepper, seeded and cut into large squares
In a medium bowl, combine the sherry, sesame oil, ginger, soy sauce, and pineapple juice concentrate. Add the shrimp or scallops. Let the shellfish marinate for 30 minutes in the refrigerator.
Prepare an outside grill or oven broiler by placing the rack 6 inches from the heat source. Remove the shrimp or scallops from the marinade. Reserve the remaining marinade. Thread the shellfish onto wooden skewers and alternate them with the mango, papaya, and red pepper.
Place the skewers on the grill and frill for about 5 minutes, turning and basting with the marinade.
