It's a cousin of Cupid's Cup (http://cocktails.about.com/od/vodkadrinkrecipes/r/cherub_cup.htm) and the Red Martini Bar's (Redmond, Oregon) Cupid's Kiss!
Crisp, light, dry and fruity but not too sweet. A perfect cocktail to sip in the hot tub!
Happy Valentines Day!

1/4 cup (or handful) of fresh or frozen huckleberries
2 oz vodka
1 oz St. Germain
