Mai Tai

This was my first attempt at a Mai Tai, and I feel pretty damn good about it.

1.5 oz. light rum
.5 oz. Cointreau
1 oz. pineapple juice (canned)
1 oz. fresh orange juice
.25 oz. fresh lime juice
.5 oz. marachino juice

Poor over short glass full of ice. Add .5 oz. dark rum float. Garnish with marachino cherry and pineapple.
