UGLI FRUIT

The fruit above does not look pretty.  In fact it looks ugly and that is why it is so named.

INFO ABOUT UGLI

Ugli is a citrus hybrid between grapefruit and tangerine that grows in Jamaica. Its weird name may be spelled wrong but it really comes from “ugly” in reference to its unappealing, wrinkled skin. But the looks of the Ugli have nothing to do with the taste, it is incredibly delicious and juicy, it takes more from the sweet tangerine and less from the sour grapefruit.
As a curiosity, you should know Ugli is the only fruit in the world that starts with the letter U.
