Sweet potatoes are very popular in Japan and are put in many dishes.The traditional way is to rake up a big pile of leaves and set them on fire and put in the potatoes. That's is the yakimo or baked sweet potatoes.
This is a really good and somewhat healthy snack alternative. It's imo kenpi made from sweet potatoes. They're crunchy, sweet potato sticks frosted on the outside. Just potatoes and sugar. It's a great way to satisfy your sweetooth. I love them.
