Parsley roots are a pale creamy-white, like a parsnip, but less yellow, and are thin and slender like a carrot. They lack that woody part to their roots that large parsnips have, being tender all the way up like a carrot. They taste predominately of parsley, but also of celeriac and parsnip.
They can be eaten raw in salads or as part of a coleslaw; the organic ones I got hold of made my tongue go a little numb after eating a raw one!
Cooked, they can be used like any root vegetable in soups. Apparently, they roast very well and make excellent chips. Their slight earthiness marries well with fish especially shellfish. I found a great-looking recipe for scallops in parsley root milk by American chef Karen Brooks – one to try next!
