Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the chowder, flaking into tender pieces as it cooks.
- Potatoes
- Soften during boiling and thicken the broth with their starch.
- Crackers
- Absorb liquid and help thicken the chowder as they soften.
- Milk
- Adds richness and creaminess to the broth when stirred in at the end.
The step that matters
Boil until the potatoes are tender. Potatoes must cook fully before the milk goes in, since starch softens slowly and undercooked potato stays firm and grainy in the broth.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (fish, bread, potato, pepper, pork, milk):
- Capsicumfits better
- Tomatofits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against fish, bread, potato, pepper, pork, milk. Candidates are from the same food group and used in at least 100 recipes.
