A roux. A base for sauces of combination of fat or oil and flour, gently cooked and then mixed with stock or milk or whatever is required for the sauce, brought to the boil and simmered.
Sanguin or bloody milk cap. A mushroom quite similar to the saffron milk cap but less common. It exudes a red milk sang poivré when cut.
Red gurnard. Gurnards are strange-looking, scaly, spiky, bottom-feeding fish which use the three bottom rays of their pectoral fins to "feel" the sea bed. They have firm-textured white meat with a mild flavour. They are rich in protein, iodine and phosphorus. The red gurnard is the most attractive member of the family with pinkish-red colour and the finest flavour of the gurnards. They are all bony and tend to dryness so they are best served with a sauce. Small ones are excellent in soup. Red or grey mullet (US: striped mullet) can generally be subsituted for it, and are usually better.
Russula integra. A good edible mushroom with pinkish brown colour.
