Kiwano
Also known as African horned cucumber, horned melon, spiked melon or jelly melon among other monikers, kiwano has spiked orange skin with lime green flesh that looks like jelly and tastes, some say, like a mix of banana and passionfruit or banana, cucumber and lime. Its peel is also edible and rich in both fiber and vitamin C.
The fruit is native to sub-Saharan Africa, and it’s currently grown in Australia, Chile, Germany, Italy, New Zealand, Portugal and the U.S.
