The most important things for this preparation is to keep the ingredients as cold as possible
Combine Gin, Heavy Cream, Simple Syrup, Lemon and Lime Juice and Egg White into tin and give it a hard Whip Shake
Pour into frozen glass
Add 1.5oz cold Soda Water and place in freezer for 10 minutes
As the drink has chilled, put a straw in the center to make a hole and top off, carefully with cold Soda water until the foam rises above the rim of the glass
Garnish with 3 drops or dashes of Orange Flower Water and Zest with Orange and discard
