I saw the box of fruit for sale at a local supermarket. The fruit looks otherworldly to me. Apparently, it is grown in Chejudo. On the right, is a fruit from a tree at Gwandong University. Clearly, the fruit are different but similar. Are these the cultivated and wild varieties of the same fruit?
Anyway, what is a 'Yong-gwa'? Do you peel and eat them? Are they worth buying? Or, does anyone dare me to eat one and can I make money out of it somehow?
