This is extremely simple using just a toaster oven! How about having them as a beer snack or in your bento?
I bought some chikuwa, and wanted to make some sort of snack to go with my beer, so I came up with this off the top of my head.
This is quick and easy, so I don't have any tips. Make the mentsuyu sauce as rich as you like.
Enjoy Japanese food around the world.
