Portobello Mushroom: what every chef needs to know
In any well-stocked kitchen, Portobello earns its place: the fully grown, large-format variant of the common button mushroom. When a mushroom has fully matured and the cap is wide open (10–15cm diameter), it is called a portobello. The cap has a brown to dark brown upper surface and dark gills on the underside. The flavour is intensely umami and meatier than ordinary mushrooms due to higher concentrations of glutamate (free amino acids). Portobello are rich in selenium, copper, vitamin B2 and B3 and contain ergothioneine, an antioxidant that is relatively stable when heated. Never store portobello in plastic: this causes condensation and rapid spoilage. A paper bag is optimal.

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.
