Gently muddle the mint leaves and simple syrup in the bottom of the julep cup or glass, releasing their aromatic essence.

Fill the cup with crushed ice, packing it tightly.

Pour the bourbon over the ice, allowing it to chill and meld with the mint and syrup.

Stir the mixture gently to combine the flavors.

Top up with more crushed ice, forming a mound above the rim of the cup.

Garnish with a fresh sprig of mint.

Insert a short straw close to the mint so that the aroma can be appreciated with every sip.
