3/4 ounce Captain Morgan spiced rum
3/4 ounce light rum
1/2 ounce blue curacao
1 1/2 ounce sweet and sour
3 drops grenadine
Fill a cocktail shaker with ice. Pour in all your ingredients except for the grenadine. Shake it well and strain into an old-fashioned glass. Drop the grenadine over an ice cube and serve quickly so it looks like blood in the water.
