We like a boozy cocktail and this certainly is one. Himself made it as directed from John Cusimano's My Year in Cocktails and next time (and there will be one) I'd like to try it with the even more peppery watercress.
10 Arugula Leaves
3 or 4 Strawberries
2 oz gin (Try Aviation)
1 1/2 oz St. Germain elderflower liqueur
Pinch freshly ground black pepper
Juice of 1/2 lemon
1/4 oz agave syrup
Muddle the arugula in the bottom of a cocktail shaker with the strawberries and agave syrup. Add the rest of the ingredients with ice and shake. No need to strain but pour over crushed ice in chilled glass.
