In a saucepan, mix together the maple syrup, brown sugar, bourbon, Dijon mustard, soy sauce, granulated garlic, pure orange extract, and butter. Simmer on low heat for 5-10 minutes while continuously stirring.
Continue to simmer the rest for 5 more minutes or until the glaze thickens. Reserve 1/4 of the glaze for dipping.
Preheat your Z Grills smoker to 225°F.
Cube the salmon into uniform 1 1/2 x 1 1/2 inch pieces.
Apply the sweet rub to all sides of the salmon.
Once the smoker reaches 225°F, place the salmon on a wire rack and add it to the smoker.
Smoke for 30 minutes or until the internal temperature of the salmon reaches 125°F.
Baste the salmon with the maple bourbon glaze and continue to smoke for another 30 minutes, basting every 15 minutes.
Once the salmon reaches an internal temperature of 145°F, remove it from the smoker.
Sprinkle sesame seeds on top of the salmon.
Plate the salmon burnt ends and serve with the reserved maple bourbon glaze for dipping. Enjoy!
