For an extra layer of complexity, consider adding a dash of Angostura bitters to the shaker before mixing. Adjust the sweetness to your preference by slightly increasing or decreasing the amount of orgeat syrup. Use fresh juice for the best flavor. Bottled juice lacks the vibrancy needed for this cocktail. Experiment with different types of rum, gin, brandy, and sherry to find your perfect blend. Serve immediately and enjoy responsibly!
