Black Walnut Liqueur

Toast walnuts. Transfer to clean 1 quart jar with tight fitting lid. Add vodka and bourbon and cover tightly right away so alcohol doesn't evaporate. Let stand in a cool dark place for 1 month, shaking occasionally.

Use a fine mesh strainer to strain out walnuts. Discard. Transfer liqueur to clean container.

Bring corn syrup and water to a boil over medium high heat, stirring constantly to prevent scorching. Remove from heat and let stand until just warm. Add syrup and vanilla to liqueur, cover and age for 1 month.
