Soba (Buckwheat Noodles): what every chef needs to know
Soba are thin noodles made from buckwheat flour, with or without the addition of wheat flour. The traditional ratio is 80% buckwheat to 20% wheat (ni-hachi soba), but juwachi-soba (100% buckwheat) is regarded as the most prestigious. Making 100% buckwheat soba is extremely challenging: buckwheat contains no gluten and the dough tears easily.\n\nALLERGEN NOTE: Buckwheat is NOT on the EU Big 14 allergen list but is associated internationally — especially in Japan — with serious allergic reactions. Wheat-containing soba DOES contain gluten (EU Big 14). Always check the composition: many commercial soba products contain more wheat than buckwheat.\n\nSoba is served cold (zaru soba) or hot (kake soba). Cold soba reveals the true quality of the noodles: nuances in flavour and texture are fully visible. Sobayu is the cooking water of soba, ritually drunk in Japan as a soup after the meal.

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.
