It is made with St-Germain liqueur. St-Germain is made from Elderflower and has a distinct floral flavor. There is something almost familiar about the taste, even though I know I have never experienced it before. St-Germain is difficult to find, but if you can locate a bottle don't pass up the chance to try out this recipe.
2 Shots of Vodka or Gin
1 1/2 Shots of St-Germain
1/2 Shot of Dry Vermouth or Dry White Wine
Shake all ingredients with ice and fine strain into a chilled Martini glass. Garnish with a lemon or orange twist.
It's hard to describe how absolutely delicious this martini is. I've never tasted anything like it. The website for St-Germain also has recipes for other cocktails and yummy drinks to make with the liqueur.
Bonus: The bottle is gorgeous!
Thanks for introducing me to this Cullen!!!
