Without shame, I'll admit that the pictures of gorgeous marbled cubes on the front of this bag drew me in. Of course, the matcha flavor didn't hurt at all, since it never takes much convincing to make me buy matcha sweets. These were under $3 at a Japanese import grocery store.
The little cube dog on the bag said Cute Cube which is probably the origin of the name, CuCu. The candy is supposed to be a medley of Uji matcha, Hokkaido azuki, and condensed milk.
The candies were shaped like dice, and though they weren't quite as pretty as the picture on the bag (the actual white stripe was rather dull), they were still lovely candies. The matcha flavor was strong and immediate, with buttery and rich hints of condensed milk. There were some hints of azuki flavor, but they served the matcha well.
They never got sharp like some candies can, and they maintained their rounded cube shape throughout the entire smooth melt. The packaging was super cute, too, but I wish the wrappers were clear so that I could admire the marbled cubes in my candy dish. These were delicious, and I had no trouble eating 2 or 3 in a row. It's yet another example of matcha done well by UHA.
