Deciding to eat cod or haddock can be more complicated than it seems. They’re both popular white fish, both belong to the cod family and both are great in fish and chips, baked fish, fish cakes and seafood soups. But, they’re not quite identical.

People often look for the best fish to eat based on the taste, firmness, protein, or suitability for a specific recipe  cod vs haddock. The differences between the two fish might not be apparent at first glance on the plate.

The bright side is that it’s easy to decide between them once you consider their flavor, consistency, nutritional value, dimensions, purposes in cooking, and where they are available. The flavor of cod is mild, clean and the flakes are bigger. Haddock is slightly sweeter, and has finer flakes. According to NOAA, haddock is firm and tender and Atlantic cod has larger flakes that are less firm. (NOAA Fisheries)

The origin of Cod or Haddock 

The words cod and haddock are both old English words.

According to Merriam-Webster, the word cod is a Middle English term, and was first recorded in the 14th century. (Merriam-Webster)

Haddock is another word with a long history. Its etymology is from Middle English haddok and its first citation dates back to the 14th century according to Merriam-Webster. (Merriam-Webster)

These names are not to denote any different spellings of the same fish. They are able to name two species.

Gadus morhua is a common name for Atlantic cod. Melanogrammus aeglefinus is known as Haddock. Haddock is a smaller member of the cod family. (NOAA Fisheries)

Another good identifying feature of Haddock is a dark patch near the pectoral fin, sometimes referred to as a “thumbprint”. (NOAA Fisheries)

So in writing the word ‘cod or haddock’, unlike the spelling of questions like ‘color or colour’, it is a comparison between the two different fish.

British English vs American English Spelling

Both words are spelled the same by major British and American spellers.

Both British and American English have the following:

• cod
• haddock
• Some people use “cod fish” as a slang term for a person.
• In some contexts, codfish is synonymous with salmon.

The main problem is not spelling. It has meaning.

Term	British English	American English	Meaning
Cod	cod	cod	A school of fish, including Atlantic cod.
Haddock	haddock	haddock	Fish from a different family (the cod family)
Codfish	codfish/cod	codfish/cod	Another term for cod
Cod or haddock	cod or haddock	cod or haddock	Select either one or the other fish.

Since the names are the same in both languages of English, there’s no need to alter the spelling for a British or American audience.
