Fish Chowder
Ingredients
Directions
Prepare the fish
Skin the fish by loosening the skin at the head and pulling it down towards the tail.
Remove the bones from the fish.
Cut the fish into small pieces.
Wash the fish pieces in cold water.
Boil the head and bones in 2 quarts of hot water.
Make 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 sliced 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 and simmer gently for 10 minutes.
Taste and adjust seasoning if necessary.
Add the 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, helping thicken the broth and give body to the chowder.
- Salt pork
- Renders fat and browned flavor that carries through the whole chowder.
- All-purpose flour
- Thickens the broth into a gravy-like body as it cooks with the liquid.
- Crackers
- Soak up liquid and add body, thickening the chowder near the end of cooking.
The step that matters
Frying the salt pork until brown. Browning renders fat and creates savory, toasted flavors that the broth depends on. Pale or burnt pork gives a flat or bitter taste to the whole chowder.
Swap the onion
