Rhubarb slice and fresh rosemary sprig for garnish
Rhubarb Syrup:
240gchopped rhubarb
240mlwater
200ggranulated sugar
Instructions
To make the rhubarb syrup, add the chopped rhubarb, water, and sugar to a saucepan and bring to a boil. Reduce the heat and simmer for about 15 minutes, until the rhubarb is soft and the sugar has dissolved.
Strain the mixture through a fine-mesh strainer, pressing on the solids to extract as much liquid as possible. Discard the solids and let the syrup cool completely.
In a cocktail shaker without ice, combine the rhubarb and ginger gin, fresh lemon juice, rhubarb syrup, and egg white.
Shake vigorously for about 15 seconds.
Add ice to the shaker and shake again for another 15 seconds.
Strain the mixture into a glass filled with ice.
Garnish with a slice of rhubarb and a sprig of fresh rosemary.
Enjoy your delicious and frothy rhubarb and ginger gin sour with egg white!
