Burdock and Gobo Recipes
Burdock (Arctium minus and Arctium lappa) is a well common, wild edible plant most people will know of for it's root. Also known as gobo root, the plant is actually cultivated in Japan and has been used as a food for a long time.
There's a couple different species, but for all intents and purposes the roots are interchangeable in recipes.
Besides the root, burdock flower stalks can be cooked and makes a good vegetable, especially in soup.
Some people also scrape or peel the petioles, but I find them to be bitter and too much work to bother with when the other parts of the plant are so easy to work with.
