Remove salmon from refrigerator 15 minutes before cooking.
Heat grill or oven bto 375 degrees.
Stir marmalade, molasses, paprika and cider vinegar together.
Cut 2 pieces of wide, HEAVY DUTY aluminum foil about 6 inches longer than the salmon side. Stack the foil pieces (shiny side down) on a baking sheet and SPRAY generously with cooking spray.
Place the salmon, skin side down, in the middle of the foil. Fold the foil sides and ends up (1-2 inches) to make a shallow pan around the salmon, leaving at least a 1-inch margin around the fish. Season fish with salt and pepper. Carefully transfer the foil pan to the center of the preheated grill. Do not cover the salmon with foil or close the foil around the salmon.
Close grill and cook for 5 minutes. Spread the glaze over the salmon. Close grill and continue to cook for 5- 7 minutes more. Cook just until fish is lightly translucent in the center. It will finish cooking from retained heat.
Remove from grill and let rest a few minutes before serving. Garnish with orange zest and serve with orange wedges.
VARIATION: ROAST IN AN OVEN, PREHEATED TO 375 DEGREES. COOK 12- 13 MINUTES, UNTIL LIGHTLY TRANSLUCENT IN THE CENTER. (MIGHT TAKE LONGER.) BE SURE TO LET THE SALMON REST A FEW MINUTES BEFORE SERVING.
