Step 1: Prep the Base
Place the fresh lemon wedges and mint leaves directly into the bottom of a sturdy cocktail shaker.
Step 2: Muddle Efficiently
Use a professional flat-end muddler to firmly press the ingredients together. Press hard enough to extract the fresh lemon juice and fragrant oils from the peel, but avoid shredding the mint leaves entirely to prevent bitterness.
Step 3: Combine Liquids
Pour in the simple syrup and your choice of quality bourbon over the muddled mixture.
Step 4: Shake and Chill
Fill the cocktail shaker halfway with ice. Close the tin and shake vigorously for about 10–15 seconds until the outside of the shaker feels frosted and cold.
Step 5: Strain and Serve
Strain the vibrant liquid into a classic rocks glass filled generously with fresh, crushed ice.
Step 6: Garnish
Clap a fresh sprig of mint between your hands to release its aromatic oils, tuck it into the glass, and serve immediately.
