Do you know the story of "Momotaro" (the Peach boy)? Chances are you do, but for those of you that don't, I've found a brief version here. The millet dumplings that appear in the story are called kibidango (millet cakes). These are made like mochi (rice cakes) but instead of rice they use millet. They were really soft and covered with kinako (powdered soy bean).
The prefecture of Okayama boasts that they are the home of Momotaro--though no one really knows for sure. These were omiyage (a souvenir) from Maui Luna, Okayama is her hometown. (Thanks Maui Luna!)
p.s. Today is Satoshi's birthday. I'm not sure what type of cake to make but hopefully I'll get around to it!
