Fill a highball glass with ice cubes, leaving about an inch from the top. The ice should fill roughly two-thirds of the glass to ensure proper dilution and temperature.

Pour the Southern Comfort, amaretto, and sloe gin over the ice. These three liqueurs form the foundation of your Alabama Slammer, creating that signature sweet and fruity base.

Add the orange juice and pineapple juice to the glass. These juices provide the refreshing tropical notes that balance the sweetness of the liqueurs.

Slowly pour the grenadine down the side of the glass or over the back of a spoon. Watch as it settles to the bottom, creating that beautiful sunset gradient.

Give the drink a gentle stir to slightly blend the flavors while maintaining some of the beautiful color variation. Garnish with an orange slice and maraschino cherry on a cocktail pick.
