Yōkan

A Japanese confection of red or white bean paste, agar, and sugar, sold in blocks and sliced for eating.

Yōkan originated as a Chinese mutton soup called yang geng. After meat was abandoned in Japan, it was adapted using barley or azuki bean paste. Agar’s invention in the 1600s enabled its modern form, finalized around 1800 in the Edo period.
