Tomatoes or Kumatoes?

I don't know if I understood this one. These tomatoes looked unripe (or even spoiled?), but were apparently intended to be this way, as they were some kind of cross-bred variety from Europe. It was supposed to be stronger in taste, which it was, but I didn't find it so pronounced that I was motivated enough to get these "kumatoes" over regular tomatoes.

Indeed, I've been more impressed with Japanese produce instead. These were similarly expensive though: S$7 (US$5) for a box of six. And the labels suggested that these came from Malaysia rather than Europe, so I'm not sure what the deal was. Maybe I'll do a side-by-side taste test some other time to really try to pin down the difference.
