60mL Jamaican Rum
15mL Orgeat Syrup
7mL Rock Candy Syrup (if you can't find this, it is water supersaturated with sugar, so any similar substitute is likely to work)
Juice of 1 fresh lime
Pour the ingredients over shaved ice in a double old-fashioned glass, shake it well, add one spent lime shell and garnish it with a sprig of fresh mint.
