Imo-Zenzai

Here is a picture of today's teatime at Musashino-Sabo (武蔵野茶房) in Tachikawa station. :)



Zenzai is very much similar to Read Bean Soup, and perhaps there is no difference in English.
You can find out some more examples here.
Also Imo is usually potatoes, but in this case sweet potatoes.

In Japan, the most popular thing served with Zenzai is chestnut. Otherwise, plain zenzai is common. But, anyway, Imo-Zenzai is also worth trying. :)
