You've probably seen this tomato-doppelgänger-looking fruit at your local market. Persimmons, which originate from Asia, are sweet like dates but most similar in consistency to mangos. An excellent source of dietary fiber, they help your body fight inflammation and are rich in vitamins C and B.
The two most commonly found varieties here in the United States are Fuyu, which can be eaten when more firm and look more like a tomato, and Hachiya, which need to be soft before being consumed. If you eat Hachiya before they're ripe, they make your tongue tingle—really! While it's a fun trick, I don't recommend it.
They're a fun way to brighten up your winter food, and they go out of season in North America in February, so get to cookin'!
