Why is your guacamole so bitter?

Guacamole can taste bitter if the avocados used are overripe or have begun to spoil. The presence of certain compounds in the fruit, such as tannins, can also contribute to a bitter flavor, especially if the avocados have been exposed to air for too long. Additionally, using overly ripe or unbalanced ingredients, like too much lime juice or an insufficient amount of salt, can affect the overall taste. To improve the flavor, ensure you use fresh, ripe avocados and adjust the seasoning to your preference.
