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
Scrub the clam shells and place them in a kettle over the fire.
Cover with boiling water and remove from heat as soon as the shells open.
Save the water and set it aside.
Make the chowder
In the kettle, fry the chopped salt pork until brown.
Add the reserved clam water and clam juice, potatoes, and sliced onions.
Simmer for 1 hour and 15 minutes.
Add the milk (or water) and cook for an additional 15 minutes.
Stir in the clams and serve.

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 bite of the chowder.
- Salt pork
- Renders fat that browns and carries savory flavor through the whole pot.
- Potatoes
- Soften during simmering and thicken the chowder while giving it body.
- Onions
- Soften and sweeten as they cook, building aromatic depth in the base.
- Milk
- Adds creaminess and richness to the broth; water may be used instead.
The step that matters
Stir in the clams and serve. Clams turn tough and rubbery when overcooked. Adding them at the end, after the long simmer, keeps them tender.
