Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rock cod
- Provides the main flaky protein that becomes tender and separates into pieces as it cooks.
- Salt pork
- Renders fat into the kettle, adding savory flavor to the base.
- Crackers
- Absorb liquid and swell, helping thicken the chowder and give it body.
- Potatoes
- Release starch as they cook, adding body and thickening the broth.
- Onions
- Soften and turn sweeter as they cook, adding aroma and depth.
- Milk
- Forms the creamy liquid base that gives the chowder its richness.
The step that matters
Heating the milk over the fire. Milk scorches easily on the hot bottom of a kettle and can curdle or separate if it boils hard. Heating it gently and stirring helps keep the chowder smooth.
