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
Wash the clams thoroughly and place them in a pot with ½ pint of water.
Cook until the shells open, then remove the clams from the shells and chop finely, saving the clam water.
Cook the base
Fry the salt pork gently until browned, then remove the scraps.
In the same pan, fry the chopped onions until delicate.
Add 1 quart of hot water, clams, clam water, and pork scraps to the chowder kettle.
Once boiling, add the potatoes and cook until tender.
Thicken and finish
Thicken the chowder with 1 cup of powdered crackers and stir in 1 quart of fresh milk.
If too rich, add more water and season with black pepper.
For extra flavor, add sliced tomatoes before serving.

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 body of the chowder.
- Salt pork
- Adds fat and savory flavor as it browns and renders into the base.
- Potatoes
- Soften during cooking to give the chowder body and bulk.
- Powdered crackers
- Thicken the chowder as they absorb liquid and swell.
- Fresh milk
- Adds creaminess and mild sweetness, softening the broth.
The step that matters
Thicken with crackers after the potatoes are tender. Powdered crackers swell and thicken the liquid quickly, so adding them too early or in large amounts can make the chowder gluey. Stirring them in once the potatoes are cooked lets you control the thickness before the milk goes in.
Swap the tomato
The recipe marks tomato as optional. How well each one fits the dish's main ingredients (clam, pork, onion, potato, milk, pepper):
- Capsicumfits better
- Tomatothe original
- Asparagusfits about as well
- Carrotfits about as well
Fit is the average pairing score against clam, pork, onion, potato, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
