Water Chestnuts: what every chef needs to know
Water chestnuts are an aquatic plant from the sedge family, native to East and Southeast Asia, producing a round, edible corm. Despite the name, water chestnuts bear no botanical relation to the (sweet) chestnut: they are a water-dependent monocot tuber crop. Fresh water chestnuts have a crunchy, crispy texture that is largely retained even after prolonged cooking, a property unique in the plant world. This makes them ideal for wok preparations and dim sum fillings where textural contrast is essential. Fresh water chestnuts have a lightly sweet, crispy flavour, comparable to raw apple or jicama. Canned has a less pronounced flavour but retains the typical texture well. Fresh water chestnuts are seasonally available in autumn and winter via specialist Asian suppliers. Water chestnuts are not an EU-14 allergen and contain no gluten or lactose. The relatively high carbohydrate content (23.9g/100g) is relevant when calculating food costs for specific dietary requirements.

Water Chestnuts: preparation techniques
Exact temperatures and times for HACCP compliance. Core temperature is leading for poultry and pork.
Store cut water chestnuts in cold, lightly salted water until needed; oxidation and discolouration occur quickly. Prepare no more than 2 hours before serving.
Add water chestnuts late in the wok process; prolonged stir-frying reduces their crunch. Slice for even cooking and maximum texture.

Milk allergen and lactose intolerance
The EU-14 allergen "Milk (including lactose)" covers two distinct conditions, both of which require declaration: (1) cow's milk allergy, an immunological reaction to milk proteins (casein, whey), and (2) lactose intolerance, an enzymatic deficiency (lactase) preventing digestion of milk sugar. Both groups must be informed separately on the menu. Lactose-free is not the same as milk-protein-free: a guest with cow's milk allergy may still react to lactose-free products.
