If broiling fish, preheat oven broiler. If barbecuing, lightly oil grill and preheat barbecue to high. After brushing both sides of fish with teriyaki mixture, place fish on a lightly oiled broiler pan or barbecue grill. Broil about 4 inches (10 cm) from broiler element or on barbecue grill with lid closed. During cooking, brush often with any leftover teriyaki mixture until fish is cooked through, from 2 to 3 minutes per side for rare tuna and from 4 to 5 minutes per side for salmon or swordfish.
