The average American consumes 27 pounds of bananas every year. If you're not getting your fair share, try this classic drink—you'll catch up in no time. Chill the cocktail glass by filling it with ice and water, and set it aside. Crush the ice in the blender. Peel the banana and break it into small chunks. Place the small chunks of banana into the blender. Pour in the light rum, banana liqueur, lime juice, and simple syrup. Blend the ingredients for about 15 seconds, or until smooth and creamy. Empty the now-chilled cocktail glass. Pour contents into the glass and serve. Most bananas are grown in tropical regions—except in Iceland, where they flourish in geyser-heated soil.
