Simply put, a shrub is a vinegar-infused fruit syrup, an old-time mixer for sparkly summer drinks. Tart, sweet, and acidic, a basic shrub uses one part fruit, one part sugar, and one part vinegar, but the possibilities for experimentation are endless. Try this Strawberry Balsamic Shrub cocktail. It’s like drinking summer.
Combine the liquor and the shrub in a cocktail shaker. (Note: I listed bourbon, gin, or rum in the ingredients; they are all great, but they make very different drinks. Feel free to experiment). Shake vigorously until chilled. Strain into a mason jar filled with crushed ice. Top with ginger beer, and garnish with strawberry and mint sprig.
