1. Add all the ingredients to a cocktails shaker
Fill a cocktail shaker with ice and add all the ingredients.
Shake hard for 7-10 seconds (double this if you're using egg white) to mix all the ingredients.
3. Dry shake (Optional – only required if using egg white)
Strain into a glass, remove the ice and shake again without ice.
4. Strain and serve
Either serve neat in a cocktail glass, or over ice in a tumbler.
