Why it works: Onion and potato 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 ↓
Clam Chowder
Ingredients
Directions
In a pot, cook the diced salt pork until browned.
Layer the onions, then potatoes, then clams in the pot, repeating until all ingredients are used.
Add 1 quart of water and the clam juice.
Season with pepper and do not add salt.
Cook slowly for 2 hours, stirring very little and carefully.

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 body as they cook down.
- Potatoes
- Release starch as they cook, thickening the broth and giving it body.
- Salt pork
- Renders fat that carries flavor and adds savory depth to the base.
- Onions
- Soften and turn sweet as they cook, adding aroma and depth to the broth.
The step that matters
Cook slowly for 2 hours, stirring very little and carefully. Gentle, low heat keeps clams tender instead of rubbery, and minimal stirring stops the potatoes from breaking down and clouding the broth.
Swap the onion
How well each one fits the dish's main ingredients (clam, potato, pork, pepper):
- Capsicumfits better
- Onionthe original
- Tomatofits about as well
- Asparagusfits about as well
Fit is the average pairing score against clam, potato, pork, pepper. Candidates are from the same food group and used in at least 100 recipes.
