Add all ingredients to a small saucepan over medium heat and whisk to combine.
Cook until bubbly - about 5 minutes. Then reduce heat to low and continue cooking for 15 more minutes to allow the flavors to develop.
Taste and adjust seasonings as needed, adding more whiskey for a more boozy flavor, brown sugar for added sweetness, vinegar for more tang, and liquid smoke extra smokiness.
Transfer to a jar and let cool before putting lid on. Will keep in the fridge for at least 2-3 weeks (probably longer).
