Pollack. A member of the cod family found in the eastern and north Atlantic and weighing around 1 kg (2 lb). It is dark green above and has a protruding lower jaw. They have rather grey, flaky flesh and are often salted and dried or pickled and are also commonly used for making imitation shellfish foods. Treat is as you would cod. I have heard that Somerville and Ross, in the Irish RM, describe pollock as tasting like cotton-wool with pins in it.
"Bitter orange." Seville orange (US: bitter orange). A variety of orange which is bitter, used for flavouring.
Pomelo. A citrus fruit similar in appearance to a grapefruit with one slightly pointed end. Once the thick skin is peeled, the segments need to have the tough leathery coating pulled away. Inside, the flesh can be deliciously sweet and juicy. It is better left for a few days after picking before it is eaten. There are pink and white versions. Is sometimes used in salads and savoury dishes.
Black poplar mushroom. Good in risotti or sauces.
Potash. A raising agent used to make a baked mixture light. Baking powder consists of bicarbonate of soda (US: baking soda) and cream of tartar which, if mixed with flour or starch, assists pastry and cake doughs to rise, as when it meets moisture it produces carbon dioxide which aerates and lightens the dough.
