Ingredients
Directions
Boil the fish in water for 15 minutes.
Remove the fish and add the sliced onion and potatoes to the water.
Remove the skin and bones from the fish and return the fish to the kettle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Provides the main flesh and flavor of the chowder.
- Potatoes
- Thicken the broth slightly as they cook and give the chowder body.
- Milk
- Adds creaminess and a mild sweetness to the broth.
- Onion
- Adds aroma and savory depth to the broth as it softens.
The step that matters
Adding the milk. Milk can scorch or curdle if it boils hard or sits over direct heat, so it is heated gently in a double boiler before joining the kettle. Boiling it only once and then holding it warm keeps it smooth.
Swap the onion
How well each one fits the dish's main ingredients (fish, potato, milk, butter, pepper):
