Heat vegetable oil in a 3qt saucepan over medium heat. Add red onion and cook until soft, but not brown, 2 - 4 minutes.
Add chopped garlic and jalapeño to the pan, and cook for about 30 seconds, stirring often so the garlic doesn’t burn.
Add VOM FASS American Bourbon Whiskey, and increase the heat to high. Bring the liquid to a boil. Cook until the liquid is nearly evaporated, about 2 - 5 minutes.
Stir in all the remaining ingredients (blueberries through salt) and return to a boil. Reduce heat to medium-low and stirring often, simmer until thickened for 15 - 20 minutes.
Remove the sauce from the heat, and place into a food processor or blender. Puree until smooth. If you want a thinner sauce to use as a glaze, pour through a fine mesh strainer to remove any thicker solids.
Use as you would your favorite BBQ sauce.
Pairs well with ribs, pork or chicken. You can make it ahead of time too. It will keep well in the refrigerator for up to a week.
