1 oz of St Germain (or Elderflower Cordial)
2 oz of Gin
3/4 oz of Meyer lemon juice
Fill a cocktail shaker halfway with ice and add the elderflower liqueur, gin, and lemon juice. Shake vigorously until the sides of the shaker are frosty, about 20 to 30 seconds. Strain into a chilled cocktail glass, garnish with lemon twist, and serve.
