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
Steam 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 and skim out the clams.
Pour the liquid into a dish to settle.
Once cool, cut off the heads of the clams with scissors.
Build the chowder
Fry the onion in the salt pork in the same kettle 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, adding more water if desired.
Melt the butter and stir in the flour.
Add the butter‑flour mixture to the chowder or to the hot milk before adding it.
Serve
Place crackers in a tureen and pour the chowder over them.

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 starch that soften into the chowder.
- Butter
- Adds richness and flavor, and with flour helps thicken the milk.
- Flour
- Thickens the milk and liquor into a creamy base when cooked with butter.
- Salt pork
- Renders fat that flavors the onion and the broth.
- Milk
- Makes the chowder creamy and mellows the seafood flavor.
The step that matters
Add the butter-flour mixture. Flour needs to be cooked with fat before liquid is added, or it stays lumpy and tastes raw. Blending it into hot milk or chowder helps it thicken smoothly.
Swap the onion
