Actually my kahula recipe uses vanilla beans, coffee, sugar, water and vodka. Kinda spices up the good ole Nepro. Almost makes me want to go to dialysis.
Try this with the vodka: Place the bottle in the freezer for a few hours or more. The silky liquid becomes lightly syrupy. Chase the vodka with a fine chocolate truffle. Let it slowly melt in your mouth as it joins the vodka - supposed to be lovely stuff.
