George Watkin's Mushroom Ketchup tastes half way between Worcestershire Sauce and soy sauce with 'subtle hints' of mushroom. The original ketchups were carefully brewed condiments, but are now all but superseded by convenient modern equivalents such as Bisto. Originally mushrooms were packed, caps, stalks and all, into earthenware jars, salted and placed on the back of the stove until they flowed with dark liquid. Next the jars were set in the oven and boiled, the sauce strained through muslin, and finally spiced with black pepper, nutmeg and mace. George Watkin's, established in 1830, is the most common brand around and, despite the olde worlde label, is made from mushroom powder. It is used to add flavour to gravy and to highlight the flavour of beef and game.

Mussels (US: blue mussels) are oval, blue-black marine bivalves with orange to yello-coloured meats. They grow in coastal waters and are seen in colonies on rocks from the Arctic right down to the Mediterranean. Most that are provided for human consumption are farmed, a process to which they respond well. Farming is relatively easy, and the farmed crops can be protected from the blooms of red alga, known as 'red tides' which occasionally afflict marine environments. The presence of these algae can lead to poisoning, making farmed mussels a preferred option. They are also like to be plump and well cleaned for use. The may be grown by seeding mussels in shallow waters and then dredged, which may dammage the sea bed. Alternatively and traditionally in many places in France they may be grown on wooden beams or poles, called bouchots or,elsewhere in Europe and very successfully, on ropes.
A variety of leek which can be ready with short, thick-stemmed leeks which will stand in good condition for several months from December.
Mustard means different things in different places. In the Middle East, Indian Subcontinent and Africa it is likely to mean mustard greens, the sharp green leaves of various plants of the mustard family. It could also refer to the mustard seed, a spice used in cooking. In the West it is more likely to refer to a hot condiment made by crushing mustard seeds and mixing it with any of a number of herbs and vinegar. English mustard is bright yellow, smooth and very hot, while French mustard is inclined to use the whole grains, with complex flavours and be much cooler.
