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 flaky body of the chowder as it cooks through gently.
- Potatoes
- Parboiling starches them and they thicken the broth while holding their shape.
- Salt pork
- Fried fat carries flavour into the stew pan and seasons the whole pot.
- Milk
- Adds creamy body and mild sweetness to the broth.
- Butter
- Adds richness and a silky mouthfeel to the finished chowder.
The step that matters
Add the milk at the end without boiling. Milk can curdle or scorch when it boils hard for long, so it should be added after the fish is cooked and heated gently.
