Add the gin, lemon juice, lime juice, egg white, cream, sugar, and orange flower water to a cocktail shaker. Shake vigorously, about 15 seconds.

Add a handful of ice to the cocktail shaker and shake again until the outside of the canister looks frosty, about 15 seconds. Strain into a chilled 10-ounce highball or collins glass without ice. Top off with club soda.

1 part simple syrup 2 parts citrus 2 parts cream 4 parts gin

This recipe seem to have too much citrus. Try less next time. Also try half and half instead of heavy cream.
