Plan to prepare this for dinner tonight!!!
Are you out of bourbon? Or do you need a non-alcoholic substitution?
Halfpint raises a good question. Additionally, how much is there in your recipe and how is it used?
...One scotch, and one beer.
The dish I know as "Bourbon Chicken" actually has no bourbon (whiskey) in it at all. It has something to do with the name of the sauce. It's an Asian recipe. If you post your recipe, we can see what it looks like, and perhaps offer more constructive advice.
I throw rum in a lot of recipes (when I can).
