Some of the seed flesh (that's the part you eat) carries a rather bitter taste. Some people will buy 3-4 fruits and only eat a couple of seed pods from them (the flesh is very rich).

In contrast to what the 1st respondent said, they're not a popular item among Koreans AFAIK (don't see them at my local Korean markets). They are much more popular in SE Asia (so think Thailand, Malaysia, Singapore, and probably Vietnam, Cambodia and Burma).

When they're imported here, they're generally imported frozen (some chain called RCSS sell them in select areas in Canada). I don't know if this affects the taste and flavour (not sure how ripe the fruit was in the first place).
