It is one of the Japanese lemons used in making Ponzu sauce. I don't know that it is much favored for fresh eating; but I could be wrong. I think in Florida they sometimes sell it as a Sambo lemon.

It tastes like a lemony grapefruit. Not worth growing IMHO. I have a branch on a large tree of it and get a dozen or so fruit a year. There are lot's better than sanboken lemons.

Yes, it tastes like lemonade, but imo, it's more of a novelty item than anything else. It's extremely seedy, has a thick peel, and very little flesh.

I like the flavor but like xentar said its just too seedy.
