Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the chowder, flaking into tender pieces as it cooks.
- Potatoes
- Soften during cooking and thicken the broth with their starch, adding body.
- Milk
- Adds creaminess and richness to the finished chowder.
- Butter
- Adds fat for richness and a smoother mouthfeel in the milk mixture.
The step that matters
Cooking the fish until tender. Fish cooks quickly and turns dry and tough if overcooked. Cook only until the flesh is opaque and flakes easily, so it stays moist in the chowder.
