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
Boil clams in 1 quart of water in an iron pot until they open.
Remove the clam meat from the shells and set aside to cool.
Strain the clam water back into the pot and skim it well just before boiling.
Make the chowder
Add the sliced potatoes to the boiling water.
Fry the salt pork until crispy, then remove it from the pot.
Sauté the finely sliced onions in the pork fat until soft.
Soak the crushed crackers in milk for 20 minutes.
In the soup pot, combine the pork, onions, soaked crackers, pepper, and salt.
Add the boiling water and potatoes, stirring well.
Mix the fine cracker crumbs with the softened butter and stir in the clam meat.
Simmer the chowder slowly for 15 minutes 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 flavor and meat of the chowder.
- Potatoes
- Thicken the broth slightly and add body to the soup.
- Salt pork
- Adds savory fat and flavor from its rendered drippings.
- Onions
- Add sweetness and aroma when softened in the pork fat.
- Crackers
- Soaked in milk, they thicken the chowder and add body.
- Butter
- Adds richness and fat to the finished chowder.
The step that matters
Skim the clam water before boiling. Skimming removes foam and grit released from the clams, keeping the broth clear and free of sand.
Swap the onion
How well each one fits the dish's main ingredients (clam, potato, pork, milk, butter, pepper):
- Capsicumfits better
- Onionthe original
- Tomatofits about as well
- Asparagusfits about as well
Fit is the average pairing score against clam, potato, pork, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
