Wolf-fish. Marine catfish. A fish of northern waters. It is medium oily and white-fleshed. Since it eats shellfish, its own flavour is good. Its jaws are strong and it has a blunt head which lend to its unattractive appearance and which is why it is normally sold filleted or in cutlets. It has few small bones and can be used in the same way as monkfish (US: angler fish), in stews or grilled. It is sometimes sold as rock salmon or rock turbot.
Spinach beet or mangel wurzel (US: Mangold), similar to Swiss chard. It is used as animal fodder. Like Swiss chard it comes with red or white swollen stems. Known as mangold in the United States. The leaves can be prepared in the same way as spinach, the stems like cardoon. It also means Chinese leaves.
