Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Provides the main flaky fish body of the chowder.
- Potatoes
- Release starch as they simmer, thickening the broth and giving body.
- Salt pork
- Renders fat that carries flavour through the frying of the onion.
- Milk
- Adds richness and creaminess to the simmered broth.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
The step that matters
Simmer the haddock and potatoes gently. Fish is delicate and breaks apart under a hard boil, while potatoes need enough simmering time to soften fully. Keeping the liquid at a gentle simmer protects the fish texture and cooks the potatoes evenly.
