Fill a cocktail shaker halfway with ice. Add vodka, gin, tequila, triple sec, spiced rum, sour mix, pineapple juice, orange juice, and cranberry juice.
Shake for 10–15 seconds until well chilled.
Fill a hurricane glass with fresh ice and strain the shaken mixture into the glass, leaving a little space at the top.
Slowly pour the blue raspberry syrup down the side of the glass or over the back of a bar spoon so it sinks and creates layers.
Let the colors settle for a few seconds. Garnish with an orange slice or a cherry and serve immediately.
Notes
Use fresh juices for brighter flavor. Adjust strength by reducing the juices for a stronger drink or skipping the tequila for lighter. Pour the syrup slowly—its higher density helps it settle for that sunset effect.
