In a blender or food processor, combine first 4 ingredients (blackberries through salt); blend until smooth then set aside. Sprinkle salmon evenly with salt and pepper.
Melt the ghee (or coconut oil) in a large skillet over medium-high heat; add salmon fillets and sear for 3 to 5 minutes per side or until fish flakes easily when tested with a fork; remove from skillet and keep warm.
Add sauce to the skillet; bring to a boil then reduce heat and cook for 10 minutes or until reduced. Serve sauce over salmon.
