Haddock is a type of white-fleshed fish in the cod family. It is found in the North Atlantic region, and it features heavily in the cuisine of the surrounding regions. It may be sold fresh, frozen, or smoked. It is rarely preserved by salting.
Haddock may be smoked to preserve it and give it flavor. One variety of smoked haddock is Finnan haddie, which is cold-smoked over peat. Arbroath smokie is hot-smoked.
