How we make it

1. Add the gin, Cointreau, lemon juice, and egg white to a cocktail shaker without ice. Shake for 15 seconds.

2. Add the ice to the cocktail shaker. Shake again for 30 seconds.

3. Strain the drink into a martini or cocktail glass; the foam will collect at the top. Serve garnished with a lemon twist or lemon wedge.
