Muddle mint, cucumbers, lime juice and simple syrup in shaker. Bruise, but don’t abuse. Add bourbon. Shake with ice and strain into a chilled double old fashioned glass.
Garnish with mint sprig and a cucumber slice.
*For honey syrup, combine 3 parts honey to 1 part hot water. Stir until finely dissolved and store at room temperature. One batch should keep for two weeks.
