Pig-nuts or Earth-nuts are the tuberous roots of Conopodium denudatum (Bunium flexuosum), a common weed in old upland pastures; it is found also in woods. This root is really of a pleasant flavour when first eaten, but leaves an unpleasant taste in the mouth. It is said to be much improved by roasting, and to be then quite equal to Chestnuts. Yet it is not much prized in England except by pigs and children, who do not mind the trouble of digging for it. But the root lies deep, and the stalk above it is very brittle, and "when the little 'howker' breaks the white shank he at once desists from his attempt to reach the root, for he believes that it will elude his search by sinking deeper and deeper into the ground" (Johnston). I have never heard of its being cultivated in England, but it is cultivated in some European countries, and much prized as a wholesome and palatable root.
