In a small saucepan, combine whiskey, pineapple juice, vinegar, paprika, garlic, and shallots or onions over medium heat. Bring to a boil and reduce until thickened and liquid is mostly evaporated. Stir in honey, tomato paste, and Worcestershire. Remove from heat and set aside until almost ready to serve.
In a small bowl, combine the brown sugar, salt, and spices for the salmon. Rub on the top side of the salmon fillets. Line a baking sheet with foil and spray with baking spray. Set aside.
In a large pan, heat the oil until it is very hot. Sear the salmon, rub side down until browned, about 2 minutes. Transfer to lined baking sheet with the browned side up. Once all of the fillets are seared, bake until the fillets flake easily and the salmon is done, bout 10 minutes.
Briefly reheat the beurre blanc sauce until hot but not boiling and then remove from heat. Stir in the cubed butter until melted. Spoon sauce on plate and place fillet on top. You can also spoon over the fillets.
Notes
Serve with creamy rice and roasted asparagus for a delicious meal!
