Notes: To make simple syrup, combine 1 cup water with 1 cup sugar in a small saucepan and heat over medium heat, stirring constantly, until sugar is dissolved. Cool before using. Simple syrup will keep in a sealed container in the refrigerator for up to 5 days.

In a cocktail shaker, muddle the cucumber slices with the lime juice and simple syrup until the cucumber has completely dissolved.
