In a medium saucepan, combine all ingredients except for the bourbon.

Step 2

Bring to a boil over high heat, then reduce the heat to low and simmer, stirring occasionally, for 10 to 15 minutes, or until the color deepens and the sugars caramelize.

Step 3

Season with salt, if needed, and stir in the bourbon. Let cool completely before refrigerating.
