How to Make a Boston Sour Cocktail
What happens when you take a classic Whiskey Sour and add egg white? It becomes a Boston Sour by name. But oh, what a difference an egg makes!
Serve in – Coupe glass
Garnish – Lemon twist
Ingredients
45ml Bourbon (We suggest Woodford Reserve Straight Bourbon Whiskey)
20ml Lemon juice, freshly squeezed
10ml Simple (sugar) syrup or agave nectar syrup
Egg white (or Aquafaba for a vegan alternative)
Angostura bitters
Method
Combine all ingredients in a cocktail shaker without ice and shake vigorously (this is called a Dry Shake) – this allows the protein in the egg to form foam, instead of being diluted by the ice
Add ice and shake vigorously – this cools the drink and strengthens the foam
Double strain contents into a coupe glass, or short ice-filled glass
Add a few dashes of bitters on top
