Season 6 oz center cut salmon filets/3 oz per person with kosher salt and freshly ground black pepper and set aside for up to an hour before cooking.
Heat vegetable oil for searing salmon in a medium sized skillet over medium high heat and add the salmon filets, skin side down. Sear for 3 minutes undisturbed. Brush 1 tbsp hoisin sauce over the top of the salmon while it's searing on the first side.
Flip salmon and sear the second side for 3 minutes.
