On the Pewter Cups
"The purpose of the cups isn't immediately clear to most drinkers because they are holding them wrong. Julep cups should only be held by the top or the bottom so that the crushed ice inside them can create a frost on the outside." (SOURCE)
2 1/2 oz bourbon
2 sugar cubes or 1/2 oz simple syrup
4-5 mint leaves
Muddle mint and sugar together in a Pewter Julep Cup (Or a collins glass) until well dissolved and mint is aromatic, add the bourbon, fill with crushed ice and stir well until glass becomes frosty, garnish with mint sprig
