Cut the skin off the Mahi Mahi fillets. Coat the fillets with olive oil. Sprinkle with sea salt, a little bit of sugar, toasted sesame seeds, cracked black pepper, garlic powder, red pepper flakes, and pour a little soy sauce over the fillets.
Grill over direct heat at 400 degrees for about 10 minutes, flipping once. About a minute before removing, brush Whiskey Peach Glaze on the fillets and remove from the grill.
Whiskey Peach Glaze: In a sauce pan over medium heat, combine 2/3 cups of Jack Daniels, two cups of puréed peaches, 1 cup of puréed red onion and red bell pepper, one cup of brown sugar, half a stick of butter, two tablespoons of minced garlic, salt, paprika, cayenne pepper. Reduce down for about an hour.
