Romanesco: what every chef needs to know
In any well-stocked kitchen, There earns its place: a reason Romanesco shows up on so many prep lists: it is a cabbage variety botanically related to cauliflower and broccoli. The characteristic fractal structure makes it one of the most photogenic vegetables in commercial kitchens. Romanesco contains high concentrations of vitamin C (93mg/100g, almost double that of broccoli) and glucosinolates, which are partially broken down during cooking; light preparation retains more bioactive compounds. A HACCP consideration: vitamin C is unstable when heated above 70°C (158°F) and dissolves in cooking water; steaming or brief blanching is preferable to long boiling. Romanesco is seasonal from August to December in Northern Europe; imports are available year-round.

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.
