Stormy Night recipe

This was bestowed on me from Wildfire Chophous in Oakbrook, IL. I'm not sure if they invented it, but I can't find it anywhere else. Absolutely delicious!

Note: Amounts are for a single cocktail, multiply as necessary, even in a pitcher.* Coat the rim of the Martini glass with your choice of sugar (I prefer plain large crystal sugar). Pour the 1 oz. of Sour Mix into the bottom of the glass. Mix the other 3 ingredients with half a mixer of ice. Shake thoroughly. Fill the glass and enjoy! Add a Pineapple or other tropical fruit as your garnish.
