If you are interested in a dish of burdock roots, I would like to show how to prepare them.
1 Remove a cane and leaves.
2 Scrape a root with a knife or scraper.
3 Slice it.
4 Soak sliced roots in water for a few minuets for removing scum.(Important for making the taste better!)
5 Boil the roots and other vegetables with your favorite soup.(My wife used a Miso-soup in this case.)
6 Miso-soup with sliced carrots and burdock roots.Sliced shiso leaves (green perilla) are added as condiment.
Burdock roots are very popular and known as a fiber-rich vegetable in Japan.
