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
Prepare the clams
Boil clams in 1 pint of water until they open easily.
Remove the heads and chop the hard portion finely.
Make the base
Fry the fat pork until thoroughly cooked, then add the sliced onion and cook until soft, being careful not to burn it.
Cook the sliced potatoes in a small amount of water until tender.
Combine and serve
In a kettle, combine the clam broth, potatoes, prepared clams, and onion with fat.
Add pepper and salt if necessary, ensuring there is enough broth to cover the mixture.
Let it simmer slowly, then break in some crackers.
When ready to serve, stir in at least 1 pint of milk or more to taste.

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 chewy bits that define the chowder.
- Fat pork
- Adds savory fat and flavor to the base as it renders and cooks.
- Potatoes
- Thicken the broth slightly and give the chowder its body and bulk.
- Crackers
- Absorb liquid and thicken the broth as they break down during simmering.
- Milk
- Adds creaminess and mellows the saltiness of the broth.
The step that matters
Frying the onion without burning it. Onions turn bitter and acrid when scorched, and that bitterness carries into the whole pot. Cooking them gently until soft releases their sweetness and builds a mild, savory base.
Swap the onion

Fit is the average pairing score against clam, pork, potato, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
