Le Marseille Fruits Fizz

Begin by adding the gin, elderflower liqueur, freshly squeezed lemon juice, simple syrup, orange bitters, egg white, and your choice of muddled fruit to a shaker without ice.

Shake vigorously to emulsify the egg white.

Add ice to the shaker and shake again to chill the mixture thoroughly.

Double strain the cocktail into a highball glass, ensuring no ice is included in the final presentation.

Top off with a splash of club soda to add effervescence.
