We can get yuzu fruit here (Florida) but couldn't get the seeds to sprout, not sure how the trees are propagated. Anyway - the fruit is underwhelming, the zest is divine, I made a yuzu kosho, it is delicious.
Sort of Meyer lemon with lime zest? The ones I got were not juicy at all, and what juice they had, I would prefer lime. But the zest of the yuzu is amazing, I do like it. You can buy yuzu sake, or a yuzu soda, to taste the flavor. Yuzu kosho is very different, savory and spicy, i made mine with grated fresh jalapenos and fermented it, absolutely divine.
Personally, I think it tastes like a lemon that went bad. Like, kind of an uncanny valley thing. It's close enough for me to think it's one thing but far enough away from me to know it is definitely not what I want.
