Persimmon is a fruit of Chinese origin which is best eaten when ripe as it tastes very bitter when it's not ripe. It has a high glucose content which is why it's very sweet and somewhat tastes like a ripe mango. I came across to this fruit at our local grocery store but they sell each fruit for almost $2! I mean...that is so not right! Well, my husband was ecstatic when he found it at the grocery because he knows how good it is and they do have a persimmon tree right at their backyard.
