http://www.seriouseats.com/recipes/2010/07/planters-punch-cocktail-recipe.html

3 ounces dark Jamaican rum (pref Coruba)
1 ounce simple syrup
3/4 ounce fresh lime juice
3 dashes Angostura bitters

1. Combine ingredients in a tall glass and fill with crushed ice. Swizzle with a bar spoon until a frost forms on the outside of the glass. The ice will settle as you do this; add more crushed ice to fill, garnish with a mint sprig.
