Add banana rum, orange juice, pineapple juice, and lime juice to the cocktail shaker.
Fill the shaker with ice and shake for 10-15 seconds until well chilled.
Strain the mixture into the prepared highball glass.
Slowly pour the grenadine down the side of the glass. It will sink to create a sunset effect.
Garnish with an orange slice and cherry.
Notes
The drink tastes best with fresh-squeezed juices rather than bottled ones.Store banana rum in a cool, dark place.The cocktail can be made virgin by replacing the rum with coconut milk.For a sweeter drink, add ½ oz simple syrup.The grenadine must be added last to create the layered sunset look.
