Coley has a distinctive coal-coloured skin with a thick white line running laterally along its body; the belly fades to pale silver. Often the least expensive fish in the cod family and is a great sustainable substitute for cod or haddock in many recipes.
Raw fillets have a pink-grey flesh that becomes paler and flaky when cooked. Coley is excellent when eaten very fresh.
It’s also known as saithe or coalfish.
