her write-up-

"According to the lady at Mitsuwa this is a special New Year dessert. The orange sections are a firm Persimmon jelly and the creamy middle section is a slice of butter. Yes, butter. When I heard it I thought 'butter' was a translation snafu but apparently I was wrong. That really is a thin piece of lightly salted butter in there.

The taste was unusual but not unpleasant. The jelly was sweeter than I expected. But the fatty saltiness of the butter cut through all that sugar. I wish there was more Persimmon flavor though.

Each piece was small, only slightly bigger than the size of your thumb....."

thanks in advance!

Is Mitsuwa the name of a confetionery? It seems that the shape of the sweet is that of "Hagoita," a traditional children's toy.

JLady- Mitsuwa is the name of a Japanese Market chain.

thanks for the info on Hagoita. pretty cool and thought the shape kinda looked familiar (own at least one real one)
