This basil cocktail is an adventurous gin sour. Made with lime juice and Green Chartreuse, this gin cocktail with basil is zesty, herbaceous, smooth and downright delicious.
Pour the gin, Chartreuse and lime juice into a cocktail jug.
Add the basil leaves and, using a stick blender, pulse 3-4 times (1 second each pulse) to break down the basil.
Strain through a fine-meshed sieve into a cocktail shaker - push down gently on the leaves with the back of a spoon or a cocktail muddler to extract any lingering liquid.
Add the simple syrup and egg white (if using).
If using egg-white: attach the lid to the shaker and dry-shake (without ice) for 30 seconds. Add a handful of ice then shake for another 30 seconds.
If not using egg-white: simply add a handful of ice to the shaker, secure the lid then shake for 30 seconds.
Once shaken strain the drink into a cocktail glass and garnish with lime zest & a fresh basil leaf
Notes
If you don't own a cocktail shaker, don't despair, it's still easy to make this basil cocktail. Just find a large sturdy jar with a screw-top lid to use instead.
If you don't have a stick blender, chop the basil leaves finely, add to the liquid and leave to infuse for 10 minutes. Muddle with a cocktail stick (or the end of a rolling pin, then proceed to strain through a sieve.
Don't skip the straining of the basil gin: There is far too much basil leaf in the drink for it to be a pleasant sip unless it's strained.
I'm happy to use a regular fine-meshed sieve for this part. But for ultimate clarity and smoothness, use a nut bag to strain the drink if you have one.
Like most cocktails, and particularly due to the fresh ingredients involved in this basil cocktail, it is best consumed straight away.
