The Shrubarb Cocktail
5.0
(6)

Creating a shrub—a vinegar-based syrup—is a quick way to add sweetness and acid to any cocktail. The one used here uses tangy rhubarb and gets a slight kick from fresh ginger. Want a non-alcoholic version? Just skip the gin.
The ginger-rhubarb shrub can be made up to a week in advance and stored in the refrigerator. The shrub makes enough for 12 cocktails.

Preparation
For the ginger-rhubarb shrub:
Step 1
Combine rhubarb, ginger, vinegar, and sugar in a medium saucepan over medium-high heat. Cover and bring to a boil, then reduce heat to low. Cook, stirring occasionally, until rhubarb is completely broken down and strands are visible, 10–15 minutes.
Step 2
Using a fine-mesh sieve or a colander lined with cheesecloth, strain mixture into a glass container. Let cool to room temperature, then chill.
For each cocktail:
Step 3
Combine gin, lime juice, and 1 1/2 ounces reserved ginger-rhubarb shrub in a cocktail shaker. Fill shaker with ice and shake until outside of shaker is frosty, about 30 seconds. Strain into an ice-filled Collins-style glass, filling three-quarters full. Top off with club soda.
