So, according to your wife's remarks, there is also actually a round green (immature) TAENG THAI (TAENG THAI ON). That is another bit of new information. I was under the impression that the immature ones were a long oblong shape.

The way she explained it to me is that any TAENG THAI (Thai melon) eaten in the green or immature stage is simply called TAENG THAI ON (young Thai melon).

Thanks Pla shado,

I understand. Much appreciated.
