Step 1

In a cocktail shaker, muddle the cucumber, mint and agave nectar until the cucumber offers no more resistance.

Step 2

Fill the shaker with ice, then pour in the lime juice and gin. Put the lid on your shaker and shake until the cocktail is thoroughly chilled, about 20 seconds.

Step 3

Strain the mixture into a martini glass. Garnish with a tiny sprig of mint, if you’d like.
