Walnut Oil: what every chef needs to know
Walnut oil is cold-pressed or warm-pressed oil from the kernels of the common walnut. Cold-pressed (extra virgin) walnut oil has a low smoke point (approximately 160°C/320°F) and is NOT suitable for heating: the polyunsaturated fatty acids (omega-3 ALA: around 10.4g/100g; omega-6 linoleic acid: roughly 57g/100g) oxidise rapidly under heat and produce harmful aldehydes and a bitter taste. Walnut oil contains the highest ALA content of all common nut oils, making it nutritionally interesting for omega-3-enriched preparations. In commercial kitchens walnut oil is used exclusively cold: as a finishing drizzle over soups, warm pasta and carpaccio, or as a base for vinaigrettes alongside bold flavours (goat's cheese, radicchio, pear, celery). The characteristic bitter, woody flavour with a rounded nutty finish requires restraint: more than 20–25% in a vinaigrette will dominate. Always store in a dark, cool location; use within 4–6 weeks of opening.

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.
