Kingston is a main crop potato, good for boiling. Pale yellow skin and cream flesh.
The king trumpet mushroom is a large mushroom with a thick, meaty white stalk and soft brown cap, the largest of the oyster mushrooms, found from spring until the end of autumn (US: fall). Similar to the poplar mushroom, but not particularly well-regarded for cooking, though its texture and flavour are remarkably reminiscent of abalone. It may be eaten either fresh or dried, roasted or baked. (If gathering mushrooms you must be absolutely certain what you have before you eat them as many are very poisonous.)
Kipfler is a cigar shaped variety of potato with yellow skin and meaty flesh.
Kipper is generally applied to kippered herring. It is split down the back, butterflied, cured in brine and then smoked. They are traditionally golden coloured. Cold smoked kippers need to be cooked, while hot smoked kippers do not. They are sufficiently oily not to need cooking in butter while poaching them removes the distinctive smoky flavour. They can be microwaved for three minutes, which retains the smoky flavour and prevents them from being too oily. They are generally coloured artificially.
A large dark purple eating plum with greenish-yellow flesh and an outstanding sweet flavour. Needs a pollinator.
The factory-made cheese is mild and flavourless, but it is still possible to obtain farm-made versions, such as Kirkham's. Lancastrians claim that it was the original 'toasting cheese' and its consistency certainly lends it to cooking.
