Tirol has decided that iyokan, which is the second most widely produced citrus fruit in Japan after mikan (small Japanese oranges which are similar to Clementines), is a good choice for one of their chocolates. Frankly, I concur, and I hope to locate a bag of these beauties at one of the local Japanese markets in the not too distant future.
There are two types of iyokan chocolates in the bag. One is a cookie variety, which I'm sure just has Tirol's trademark bland crispy little biscuit with some orange sauce on it. The other is a marshmallow with orange sauce over it. Even though this is white chocolate, the bitter notes of iyokan show potential for off-setting the cloying nature of it.
