Which ingredient is NOT included in a Zombie cocktail?

In a Zombie cocktail, the classic recipe typically includes both light rum and dark rum, along with a combination of fruit juices such as lime juice, apricot brandy, and often pineapple juice, along with other ingredients to enhance its tropical flavor profile. Grenadine is also a common ingredient that adds sweetness and color to the cocktail.

Pineapple juice, while popular in many tropical cocktails, is not universally required in all variations of the Zombie cocktail. Its absence doesn’t negate the drink's classification, as recipes can vary significantly, and many traditional versions exist that do not include it.

This understanding allows for flexibility in cocktail creation, but when considering the standard components of a Zombie, pineapple juice can sometimes be considered optional compared to the foundational spirits and other flavoring agents that define the cocktail.
