Which ingredient is a main component of the Jelly Bean cocktail?

The Jelly Bean cocktail primarily features Anisette as a key ingredient. Anisette is a type of liqueur that has a strong anise flavor, which is essential for achieving the characteristic taste of the Jelly Bean cocktail. This liqueur complements other ingredients in the drink and contributes to its sweet and licorice-like profile, making it a recognizable choice when preparing this cocktail.

The other ingredients listed, such as Blackberry Brandy and Dark Creme de Cacao, while they may be used in various cocktails, do not provide the signature flavor that typifies the Jelly Bean cocktail. Light Rum, too, is not typically associated with this particular drink. Anisette distinctly defines the Jelly Bean's flavor, setting it apart and ensuring its place in cocktail menus.
