Classic Whiskey Sour

Quick version:Pour the whiskey, the fresh lemon juice and the sugar syrup into a shaker; add the egg white if you use it and dry shake without ice until it foams. Add ice cubes, shake until ice cold and strain over fresh ice cubes into a tumbler. Garnish with a lemon zest.

1. Pour 6 cl STORK CLUB Straight Rye Whiskey into a shaker — a drink is only as good as its weakest ingredient.
2. Add 3 cl freshly squeezed lemon juice — never bottled lemon juice, and not lime.
3. Add 2 cl sugar syrup, keeping the balance of sweet and sour.
4. Optionally add 2 cl egg white for a foam crown, or leave it out or use aquafaba or a cocktail foamer instead.
5. With egg white or a substitute, first shake without ice — a dry shake — until a fine foam forms.
6. Add ice cubes and shake until the drink is ice cold.
7. Strain over fresh ice cubes into a tumbler, garnish with a lemon zest if you like, and serve.
