Shake, strain into cocktail glass. Squeeze grapefruit peel to release essences, but don't drop in drink.
For Chicago natives only I suppose... It's hard to find malort outside the city.
Created by Brad Bolt of Bar DeVille, Chicago as a reasonable way to drink malort. The bitter grapefruit notes of malort combine beautifully with the elderflower aromas and flavors to create what I think is one of the best St. Germain cocktails I've had, and it performed well in the 2009 Can Can Classic, a St. Germain sponsored cocktail competition.
