Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that adds savory flavor and crisp bits to the chowder.
- Potatoes
- Form the body of the chowder and soften to thicken it slightly as they cook.
- Fresh cod or haddock
- Provides the main protein, flaking into tender pieces as it cooks gently in the liquid.
- Canned tomatoes
- Add acidity and sweetness that give the broth its tangy, rounded flavor.
- Milk
- Adds richness and creaminess to the broth, mellowing the tomato acidity.
The step that matters
Heat the milk only until scalded. Milk can curdle or scorch if it boils hard, especially with acidic tomatoes. Heating gently until steaming keeps the broth smooth and creamy.
Swap the onion
How well each one fits the dish's main ingredients (pork, potato, haddock, pepper, tomato, milk):
- Capsicumfits better
- Carrotfits about as well
- Onionthe original
- Spinachfits about as well
Fit is the average pairing score against pork, potato, haddock, pepper, tomato, milk. Candidates are from the same food group and used in at least 100 recipes.
