Is tahini paste suppose to taste very bitter?

Tahini, a sesame seed paste, should not have an overtly bitter taste. While it naturally possesses a nutty and slightly earthy flavor, excessively bitter tahini might indicate spoilage or mishandling.

Here are a few reasons why your tahini paste might taste bitter:

Oxidation: Exposure to air can oxidize the natural oils in tahini, resulting in a rancid flavor. Check the expiration date on the tahini and ensure that it has been stored properly in an airtight container.

Exposure to sunlight or high temperatures: Keeping tahini in warm conditions or exposing it to direct sunlight can also accelerate the oxidation process and contribute to a bitter taste. Store your tahini in a cool, dark place.

Old age: Tahini can gradually lose its freshness over time, even when stored properly. If the tahini has been sitting for an extended period, it may develop a bitter taste.

If your tahini paste tastes excessively bitter, it is best to discard it and purchase a fresh jar. When buying tahini, look for a brand with a good reputation for quality and freshness.
