Water chestnut. The corm of a type of a water grass or sedge. They are used in Thai and Chinese cookery to add crunch and are also used to make desserts and drinks elsewhere in South East Asia. They are available fresh or tinned and can be used raw or cooked. They retain their shape well during cooking.
Pike-perch or zander. It is a river fish with delicate flavour. They can be differentiated from the perch by the relatively large space between their dorsal fins and their elongate, fusiform body, which is never so steeply arched behind the head as it is in the Perch. The flesh is firm and white with a stronger flavour than cod. It was introduced into the United Kingdom in the 70's and is in danger of wiping out native species of fish.
