Friends asked me to bring a drink to their holiday dinner party, so I adapted this from other drinks I’ve had, tentatively calling it:
1 1/2 oz. No. 209 gin
1 oz. Aperol
3/4 oz. fresh lemon juice
3/4 oz. ginger simple syrup*
1/2 oz. egg white
Dry shake first five ingredients for 30 seconds to integrate egg white and create foam. Add ice and shake for another 20 seconds. Strain into chilled coupe or martini glass, and garnish with a few drops cranberry bitters and sprig of rosemary.
*Ginger simple syrup can be easily made by heating 1 cup sugar, 1 cup water, and 1/4 +/- cup diced ginger root to a boil, then reducing heat and simmering for an hour. Strain into container and refrigerate.
