I don’t know if in any other countries you eat burdock. Do you? I guess it has a bit strange flavor like earth for someone, but I like to eat it as kinpiragobo or tempra. It has also some bitterness, so you should soak them into water for a while, but don’t leave them too long, or its flavor will be gone and then taste just like a bark.
I made it with only vegetables but you can add beef or ham if you want.
They’re still dirty when you get it from a store to keep its freshness, so wash well and peel its skin but thinly, again, don’t take off its flavor. The skin does have the flavor! The grannies would say no, if they saw I use a peeler. They used to rub off the skin with a back of a knife not to remove the skin too much.
