Yōkan

Yōkan (羊羹) is a wagashi made of red bean paste, agar, and sugar. It is usually sold in a block form, and eaten in slices. There are two main types: neri yōkan and mizu yōkan. Mizu means "water", and indicates that it is made with more water than usual. Mizu yōkan is usually chilled and eaten in the summer, however in Fukui prefecture it is customarily eaten in winter.
