Step 1
To make the barbecue sauce, in a heavy saucepan over medium-high heat, warm the olive oil. Add the onion and cook until soft, about 4 minutes. Add the garlic and cook just until soft, about 1 minute. Add the bourbon and cook until the liquid reduces by half. Add the ketchup, mustard, balsamic vinegar, molasses, cayenne, salt, and pepper. Bring to a boil. Reduce the heat to low and let simmer, stirring occasionally until the sauce is nicely thickened about 10 minutes. Set aside.
