What is the main ingredient in guacamole?

The primary ingredient in guacamole is avocado. This creamy green fruit is not only the base of the dish but also contributes its rich texture and flavor profile that defines guacamole. Avocados are high in healthy fats and are known for their creamy consistency, making them essential for achieving the smooth texture that is characteristic of a well-made guacamole. While other ingredients such as tomato, onion, and lime may be used to enhance the flavor or add texture and acidity, they do not serve as the foundation of the dish like avocado does.
