Preheat your oven's grill. Grease a baking tray, or line with baking parchment.
In a saucepan over medium heat, mix together the apricot juice, dried apricots, honey, soy sauce, ginger, garlic, cinnamon and cayenne. Bring to the boil, then reduce heat to medium-low, and simmer for about 20 minutes, or until reduced by about half. Stir occasionally to prevent burning. Remove 4 tablespoons of the glaze for basting, and set the remaining aside.
Place the salmon fillet on the greased baking tray, and brush with glaze. Grill for 8 to 12 minutes, or until salmon flakes easily with a fork. Gently turn over once during cooking, and baste frequently during the last 4 minutes. Serve with a drizzle of the remaining glaze.
