My verdict: Whether or not the Tochiotome strawberry indeed perfectly balances sweetness and tartness, the Kit Kat derivative is all sweet. But the strawberry flavor was a little more real than I've experienced in other strawberry-flavored candies. However, the vehicle was all wrong—it did not pair well at all with the Kit Kat wafer in the center. It really needs to be prepared some other way.
