This is a traditional sweet in Japan called ohagi or in this area, bota-mochi. Junko's mother made this. It's one of her specialties. It's made with sticky mochi rice or mochigome. The rice is pounded, but not completely as in proper omochi rice cakes. The outside is covered in anko, a sweet bean paste. I believe this is a homemade variety. There are many traditional sweets made with a red bean paste. I never knew beans could be a sweet until I came to Japan. Bota-mochi taste good. They are pretty sweet and thick and chewy. I cut this one in half to show you the inside. She makes another version with a sweet paste made from green peas.
