Combine first 4 ingredients in a saucepan. Bring to a boil; reduce heat and simmer, uncovered, 5 minutes. Remove from heat; let cool slightly. Place pineapple mixture in a blender, and process until smooth. Stir in cracked pepper. Set pineapple essence aside.
Remove skin from salmon, and sprinkle salt evenly over fillets. Combine cinnamon and next 6 ingredients (cinnamon through ginger). Rub one side of each fillet with spice mixture.
Heat oil in a large nonstick skillet over medium-high heat until hot. Add salmon, spice side down, and cook 4 minutes on each side or until salmon flakes easily when tested with a fork. Serve with pineapple essence.
