Gin, Germain and Guice

We had this drink at Prasinos in La Grange and made an honorable imitation at home. It's fresh to death and so so so yummy. Plus think of the health benefits of grapefruit juice... all that vitamin C!

1 1/2 oz. Hendrick's gin
1/2 oz. St. Germain (elderflower- no idea what that actually is)
1 t agave
1/2 small lemon, squeezed
hearty splash of Simply Pure or freshly squeezed grapefruit juice

Stir the agave and lemon juice in the bottom of a glass. Add the liquors and then ice; splash the grapefruit juice over to taste. I don't know if this drink would benefit from being mixed in a shaker and then poured over ice- they served it over crushed ice at the restaurant but unfortunately our refrigerator does not have the space age ice crushing technology that I've heard other fridges have.
