In a strainer, muddle 5 pieces of cucumber.
Add ice and rosemary syrup .
Add fresh lemon juice to the mixture.
Shake well and strain over ice in a glass. Top with tonic (recommend a natural, smaller batch tonic like Fever Tree).
Add 2 turns fresh black pepper on top.
Garnish with a torched rosemary sprig (light a small rosemary sprig on fire then immediately blow out so it smolders) and a lemon wheel/wedge.
