What is a sour cocktail?
A sour is an old-school cocktail that dates back to the 1800s. They were originally made with gin, lemon or lime juice and sugar. You can find all sorts of variations, from daiquiris and mojitos to the classic pisco sour.
Whipped egg whites can be added to add a frothy, meringue-like head that gives these cocktails a fantastic mouthfeel.
Sours were popular in the 1940s but are still delicious today. If you like margaritas, chances are you’ll love a sour!
What you’ll need to make a rhubarb gin sour:
For this spin on the classic sour, I use my homemade rhubarb syrup in place of some of the citrus juice and sugar. To make this delicious recipe, you’ll need:
Gin: The sweetness of the rhubarb syrup is a perfect complement to the botanical flavor of gin. If you’re not a fan, you can make this with vodka instead.
Fresh Lemon Juice: The lemon juice plays double duty as both a complement to the rhubarb and as the main souring ingredient to help balance out the sugar. I definitely recommend using fresh lemon juice for this cocktail!
Handy tip for juicing lemons
To get the maximum amount of juice possible from your lemon, pop it into the microwave for 5 seconds, then roll it on the counter, pressing firmly. This will rupture the cells walls, allowing you to easily extract every drop of juice. If you have more than you need, freeze the leftovers to use in another recipe!
Rhubarb Syrup: A splash of homemade syrup made from fresh rhubarb is all you need to add plenty of flavor. Don’t worry, it’s super simple to make!
Egg white or aquafaba (optional): Shaking your cocktail with egg white thickens it and gives it a rich, velvety texture. If raw egg freaks you out (I get it!) you can use aquafaba– the thick liquid from a can of beans.
How to make a rhubarb sour
Start by doing a dry shake with your egg white or aquafaba. What’s that? A dry shake is when you add an ingredient to your cocktail shaker without ice. Shaking the egg white (or aquafaba, if you prefer) before adding the rest of the ingredients will give it a chance to thicken up like a meringue. This base is what gives these cocktails their rich and creamy texture.
Once your egg white is frothy, you can add your gin, rhubarb syrup, and lemon juice. Top it off with ice and shake hard for 30-40 seconds.
Finally, strain your drink into a cocktail glass. I love using a coupe-style glass for these!
Sit back and enjoy!
