First time I can remember hearing about this fruit although I think I’ve seen them in markets. My search results for “Korean melons” fortunately didn’t fly too far in the indecent direction, I bought a box after these were recommended to me by a cop I met in the Busan supermarket. We also talked a lot about SK cinema.
They are reeeally good, like a cantaloupe//apple/vanilla ice cream flavor, very unique.

“Though there are many varieties of melons popular in Korea, the most common to North America is the chamoe, better known (in the US anyway) as the Korean melon.”
