sour
Definition
Sour is a taste that is often described as being sharp or tangy. It is one of the five basic tastes, along with sweet, salty, bitter, and umami.
Sour foods often contain acids, such as citric acid or acetic acid. These acids react with the taste receptors on our tongues, which sends a signal to our brains that we are tasting something sour.
Some common sour foods include lemons, limes, grapefruits, sour candies, and vinegar.
