Santa's Strawberry Helper is a sophisticated sipper. It is a combination of muddled strawberry, elderflower liqueur, gin, yellow chartreuse and lemon.
In a shaker, gentle muddle the strawberry. Add the remaining ingredients and shake with ice. Double-strain into a coupe. Garnish with the strawberry.
