Prepare the fresh salmon by removing pin bones with tweezers, removing the skin and cutting into 2” strips.
In a medium bowl combine oil, brown sugar, bourbon, soy sauce and fresh garlic for the marinade. Mix well.
Place salmon fillets in a large freezer bag and pour the marinade overtop.
Squeeze the air from the bag and place in the fridge for 30 minutes (up to 60 mins).
Heat a large cast iron skillet on medium heat, add butter.
Remove fish from the marinade and pour 1/4 cup into the skillet (reserve remaining marinade), turn down to medium and allow garlic to cook for about 1 min until fragrant.
Add the salmon to the skillet and cook for 2-3 minutes per side, flipping once half way through.
Remove the salmon from the skillet and add the remaining marinade.
Cook until reduced and garlic is fragrant, about 2 minutes.
Spoon glaze over the top of the salmon filets.
Top with green onions and sesame seeds.
Notes
The fish is cooked when the color is opaque, fish is firm to the touch and starts to flake off with a fork.
