This is a good luck Oshogatsu dish. It's black beans that are kind of sweet.

I was told when I was younger that you're supposed to eat one for every year of your life. So, if you're ten years old, you need to eat ten beans. I'm not sure how true that is, or if it was just a ploy to get us kids to eat them. I don't see my aunts and uncles eating that many beans...
