Gin Basil Smash

1 - Add the Basil and the sugar syrup in your shaker and muddle
2 - Add the Gin and the Lemon juice on top (2.5ml lemon juice is around half an healthy lemon)
3 - Shake with ice cubes
4 - Serve double-strained in an old fashion glass with ice cubes
5 - Decorate with basil leaves and a slice of lemon skin

Alternative: instead of muddling, you can blend the sugar syrup and the basil. This will make the basil flavour much more intensive. Beware though that it might also add some bitterness to your drink and you will the need to double-strain.
