Derby Fizz

Stir the freshly squeezed lemon juice and powdered sugar in the base of a shaker until the sugar completely dissolves.

Add the blended Scotch whisky and Ferrand Dry Curaçao liqueur to the shaker.

Shake the mixture with ice, then strain it back into the shaker.

Dry shake without ice to incorporate the egg white, creating a smooth texture.

Slowly pour two-thirds of the shaker's contents from a higher-than-normal height into a chilled Highball glass, while simultaneously pouring Thomas Henry Soda Water with your other hand. Ensure that the cocktail and soda form a single stream into the glass.

Allow the cocktail to settle for at least a minute to achieve a perfect head, similar to pouring a Guinness. For optimal results, place the glass in a glass froster, fridge, or freezer during this resting period.

Finally, pour the remaining contents of the shaker into the glass, allowing the head to rise like a soufflé.
