Much like the original, this is a bourbon-based cocktail the difference is in the preparation.
In a chilled julep cup add 10 mint leaves and your simple syrup (homemade simple syrup is best)
Lighty muddle until you can smell the oils from the mint. And muddle it lightly okay, their just mint leaves your not unclogging a toilet.
Add Bourbon AKA "loudmouth soup"
Lightly stir with a bar spoon until the cup has begun to frost and garnish with mint sprigs, then you're off to the races
