Step 1

Place a coupe or martini glass in the refrigerator or freezer for at least 5 minutes.

Step 2

Place 2 ounces grapefruit juice, 2 ounces Lillet Blanc, 1 ounce dry gin, 1/2 ounce elderflower liqueur, and 3 dashes lemon bitters in a cocktail shaker. Fill the shaker halfway with ice, seal, and shake until the outside of the shaker is very frosty, about 20 seconds.

Step 3

Pour through a strainer into the glass. Garnish with 1 strip fresh grapefruit peel.
