Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh fish
- Forms the main body of the chowder, providing flavor and tender flakes when cooked.
- Potatoes
- Soften as they cook, thickening the broth and giving the chowder body.
- Crackers
- Absorb liquid as they cook, helping thicken the chowder and add substance.
- Milk
- Adds creaminess and mild sweetness to the broth.
- Fried pork or butter
- Adds richness and fat, contributing savory flavor to the broth.
The step that matters
Boil until the potatoes are tender. Potatoes must be fully cooked before the milk goes in. Undercooked potatoes stay firm and starchy, while adding milk too early or boiling it hard can curdle or scorch it.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (fish, potato, pepper, pork, milk):
- Capsicumfits better
- Tomatofits better
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against fish, potato, pepper, pork, milk. Candidates are from the same food group and used in at least 100 recipes.
