Equipment

  • Cocktail shaker
  • Fine-mesh strainer
  • Jigger
  • Muddler
  • Bar spoon
  • Coupe glass
  • Small bowl

Ingredients

  • 2 oz bourbon whiskey
  • 3-4 fresh blackberries
  • 0.75 oz fresh lemon juice
  • 0.5 oz simple syrup or blackberry syrup
  • 0.25 oz blackberry liqueur optional
  • 1 dash black walnut bitters optional
  • 1 fresh egg white or 1 oz aquafaba for foam
  • ice cubes for shaking

Instructions

  • Add blackberries to a cocktail shaker and muddle until smashed.
  • Add bourbon, lemon juice, syrup, liqueur, and bitters.
  • Add egg white or aquafaba if using.
  • Dry shake for 15 seconds to create foam.
  • Add ice and shake again until chilled.
  • Double strain into a chilled coupe glass.
  • Garnish with a blackberry or lemon twist.

Notes

Aquafaba is a great vegan alternative to egg white for foam. Use both liqueur and syrup for stronger berry flavor, or skip liqueur for a lighter version. Chilling the glass helps maintain foam and flavor.
