Why it works: Onion and potato 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 Soup
Ingredients
Directions
Make the soup
Fry the salt pork in a pot until light brown.
Add the chopped onions and cook for about 10 minutes.
Pour in the water and add the sliced potatoes; bring to a boil.
Add the clams and mix the flour with a little water to make a paste.
Stir the flour paste into the soup along with the milk and let it boil for about 5 minutes.
Season and serve
Season with butter, pepper, and coarse sea salt to taste.
Add Worcestershire sauce if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt pork
- Renders fat that flavours the base of the soup.
- Potatoes
- Soften as they cook, adding body and starch to the broth.
- Clams
- Provide the main seafood flavour and brininess to the soup.
- Flour
- Thickens the soup as it boils, giving it a creamier body.
- Milk
- Adds richness and a mellow, creamy texture to the broth.
The step that matters
Stirring in the flour paste. Flour mixed with water first makes a smooth paste; adding it dry can clump. Stirring it in and boiling gently lets the starch swell and thicken the soup evenly.
