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.
Steak hammer. These are used to beat meat to ensure that it is tender.
