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 ↓
Clam Chowder
Ingredients
Directions
Prepare the clams
Wash the clams until clean and place them in a kettle with 1 quart of cold water.
Cook until the top clams open.
Remove from heat.
Skim out the clams.
Pour the liquid into a dish to settle.
Once cool, cut off the heads of the clams with scissors.
Make the chowder
Fry the onion in the salt pork until brown.
Remove the onion and pork.
Add the sliced potatoes and the clam liquor, pouring carefully to avoid disturbing the sediment.
When the potatoes are soft, add the clams, seasonings, and hot milk.
Add more water if desired.
Melt the butter.
Stir in the flour.
Add the mixture to the chowder or to the hot milk before combining.
Serve
Place crackers in a tureen.
Pour the chowder over the crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main flavor and texture of the chowder.
- Potatoes
- Add body and substance as they soften in the liquid.
- Butter
- Adds richness and fat to the chowder.
- Flour
- Thickens the mixture with butter to give the chowder body.
- Milk
- Creates a creamy base that carries the chowder's flavor.
- Salt pork
- Renders fat and flavor that season the onion and base.
The step that matters
Pouring off the clam liquor. Clam liquor settles sediment of sand and grit at the bottom. Pouring slowly and leaving that sediment behind keeps the chowder smooth rather than gritty.
Swap the onion

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