Fish Chowder
Ingredients
Directions
Prepare the fish
Skin the fish by loosening the skin at the head and pulling it down towards the tail.
Run a knife down the back of the fish to remove the bone, then cut the fish into small pieces and wash in cold water.
Boil the head and bones in 2 quarts of hot water.
Make the chowder
In a kettle, layer the sliced potatoes and fish, seasoning each layer with salt, pepper, and flour.
Fry the salt pork until brown, then add the sliced onion and fry slowly for 10 minutes.
Strain the pork and onion mixture over the fish and potatoes, pressing to extract the gravy.
Pour 1 pint of hot water over the strained mixture to extract more flavor.
Strain the water from the boiled head and bones into the pot, cover, and simmer gently for 10 minutes.
Taste and adjust seasoning if necessary, then add 5 crackers.
Cover and simmer for an additional 10 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cod or haddock
- Forms the main body of the chowder, flaking into tender pieces as it simmers.
- Potatoes
- Release starch as they cook, thickening the broth and giving the chowder body.
- Salt pork
- Renders fat that carries flavor through the chowder and browns to add savoriness.
- All-purpose flour
- Layered with the fish and potatoes to help thicken the broth.
- Crackers
- Soak up liquid and add body, thickening the chowder slightly at the end.
- Onion
- Softens and sweetens over slow frying, adding aromatic depth to the base.
The step that matters
Frying the salt pork and onion slowly. Browning the pork renders its fat and builds flavor, while slow frying softens the onion and sweetens it without scorching. Scorched pork turns the chowder bitter.
