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 ↓
Bean Soup
Ingredients
Directions
Prepare
Soak the navy beans overnight.
Make the soup
In a large pot, combine the soaked beans, water, onions, carrot, potatoes, pork, red pepper, and salt.
Bring to a boil and then simmer slowly for 5 to 6 hours.
Pass the mixture through a colander or sieve to separate the pulp.
Return the pulp to the pot and season with salt and Cayenne pepper.
Serve
In a separate pan, fry the croutons or bread squares in butter until browned.
Serve the soup in a tureen with the croutons on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the bulk and starch that thicken the soup once puréed through a sieve.
- Potatoes
- Break down during long simmering to add body and help thicken the soup.
- Onions
- Build savory depth as they soften and sweeten during the long simmer.
- Pork
- Adds meaty flavour and richness to the broth as it simmers.
The step that matters
Simmering slowly for 5 to 6 hours. A gentle simmer lets the beans and potatoes soften fully so they can be pushed through a sieve smoothly. A hard boil can break up the mixture unevenly and make the soup cloudy or grainy.
