I recently saw these at the market...Toscana Violets, are grown in Kumamoto (Kyushu)...they are cherry tomatoes...198 yen (about US$1.98 for 7)
On the label, they say they are supposed to resemble the feel of grapes in your mouth.
They are a deep purply-brown.
The juice that comes out from it was a little brownish.
The seeds kinda tiny.
So, how did they taste? Hmm, nothing to make me go back out and get more, they tasted like cherry tomatoes, not sweet nor sour, maybe a little tart, but it was great to try.
By the way, I took some of those tiny seeds and hopefully we'll have our own Toscana Violets to harvest.
