Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main seafood flavor and the chowder's characteristic texture.
- Salt pork
- Rendered fat and browned bits add savory depth to the broth.
- Potato
- Adds body and starch that makes the chowder heartier as it cooks.
- Milk
- Adds creaminess and mellows the saltiness of the broth.
- Onion
- Softens and sweetens as it cooks, building aroma in the base.
- Pilot crackers
- Absorb liquid and help thicken the chowder as they soften.
The step that matters
Cooking the clam bodies with the milk. Clams turn tough and rubbery when held at a hard boil for a long time. Cooking them gently for the set hour keeps them tender while the flavors blend into the milk.
Swap the onion
How well each one fits the dish's main ingredients (clam, pork, milk, potato, pepper):
- Capsicumfits better
- Tomatofits about as well
- Onionthe original
- Asparagusfits about as well
Fit is the average pairing score against clam, pork, milk, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
