Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
General Burnside's Clam Soup
Ingredients
Directions
Make the broth
In a large pot, combine clams, onions, and water, then boil for 2 hours.
Strain the mixture to remove solids.
Make the milk base
In a separate pot, scald the milk and whisk in the flour until thickened.
Season the milk mixture with salt and pepper.
Combine and serve
Chop the clams finely, removing any black parts from the stomachs.
Combine the chopped clams with the milk mixture and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Clams
- Provide the main savory flavour and the chopped meat that gives the soup its body.
- Milk
- Forms the creamy base of the soup and carries its richness.
- Flour
- Thickens the milk as it heats, giving the soup a smooth, body-rich texture.
- Onions
- Add aromatic sweetness and depth to the clam broth.
The step that matters
Scalding and whisking the milk with flour. Flour must be whisked in while the milk is hot so it disperses evenly and thickens smoothly; adding it to cold milk or letting it sit can cause lumps and an uneven texture.
Swap the onion
How well each one fits the dish's main ingredients (clam, milk, flour, pepper):
- Potatofits better
- Capsicumfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against clam, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
