Barkeep Joe Petersen of Percy's restaurant in Seattle spikes this verdant cocktail with an "immunity tincture."
- 3 oz. green juice, such as Blueprint
- 1 1⁄2 oz. barrel-aged gin
- 1⁄2 tbsp. agave
- 5 drops immunity tincture, such as Mountain Rose Immune Care (optional)
Combine green juice, barrel-aged gin, agave, and immunity tincture in an ice-filled shaker. Shake vigorously; strain into a coupe with 1 large cube. Garnish with cucumber wheel and rhubarb spear.
