Add all the ingredients into a cocktail shaker, add plenty of crushed ice, and shake till the cocktail is chilled and slightly diluted from the agitated ice. The cocktail and the crushed ice should be poured into the glass. I used a zombie mug for this cocktail, however, you can also serve it up in a classic highball glass as well. Garnish with mint.
