Salmon Prep: Season the salmon with cayenne, salt and pepper.
Sauce: In a small bowl, whisk together the soy sauce, honey, garlic, ginger and apple cider vinegar.
Cook Salmon: Set a large skillet or cast iron pan over medium heat. Add 3 tbsp of the butter and olive oil to the pan. Once the butter has melted, add the salmon fillets (skin side down first) to the pan. Cook the salmon for about 3 minutes. Then flip the salmon over and cook for an additional 2 minutes. Then pour the sauce into the pan and decrease the heat to low. Add the lemon sliced to the pan. Simmer the sauce for an additional 1-2 minutes until it thickens. Taste the sauce and season with salt and pepper your preference. Make sure to baste the tops of the salmon during the last minute of cooking.
Garnish: Transfer the salmon to individual serving platters and garnish with chopped parley, scallions and/or sesame seeds. Serve immediately. Enjoy!
