Does anyone have any views about wild roots? I am researching this for a book at present. Has anyone had good results with wild parsnip, wild carrot, burdock or others? I find them all too tough at best good for flavouring. silverweed though is excellent. Any helpful leads on this will be credited in the book! I want to give an honest evaluation but I don't want to do that based on just my experience, which perhaps don't do these plant parts justice. redeeming root stories anyone?
