These rare black diamonds were delicious after I called my supplier in Tokyo. The prices here are expensive in comparison to Europe, and I mean as much as 3x more. But here you get quality, you pay for it, but you can find some of the best exported outside of France.
The dealer asked me what I am looking for and I said; firm, not dry and nice knobby black and no too white in the interior. They were exactly what I ordered and simply delightful.
