Fish Chowder
Ingredients
Directions
Prepare the fish
Skin the fish by loosening the skin at the head and peeling it down towards the tail.
Remove the backbone from the fish.
Cut the fish into small pieces.
Wash the fish pieces in cold water.
Make the broth
Boil the head and bones in 2 quarts of hot water.
Strain the water from the boiled head and bones into the pot when the other components are ready.
Build and simmer the chowder
Layer the potatoes and fish in a kettle, seasoning each layer with salt, pepper, and flour.
Fry the salt pork until brown.
Add the onion to the pork 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 the pot.
Simmer for 10 minutes.
Taste and adjust seasoning if necessary.
Add the crackers.
Cover the pot.
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
- Provides the main body of the chowder as flaky fish pieces that cook through in the broth.
- Potatoes
- Add starch and body, thickening the chowder slightly as they cook and break down.
- Salt pork
- Renders fat and flavor that carries the gravy and browns for a savory base.
- All-purpose flour
- Thickens the liquid as it is layered with the fish and potatoes.
- Onion
- Adds sweetness and aroma as it softens and browns in the rendered pork fat.
- Crackers
- Soak up liquid and add body to the finished chowder.
The step that matters
Frying the salt pork and onion slowly. Browning the pork and softening the onion slowly builds savory flavor in the rendered fat. Rushing this over high heat can scorch the onion and leave bitter notes in the gravy.
Swap the onion
How well each one fits the dish's main ingredients (haddock, potato, pepper, flour, pork):
