Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Drizp Pea Soup
Ingredients
Directions
Soak and cook the peas
Soak the dried peas overnight in 2 quarts of cold water.
Combine the soaked peas with 1 gallon of cold water and the bacon or salt pork in a large pot.
Bring the mixture to a boil. Skim the surface.
Cover and let simmer for 3 to 4 hours until the peas are very tender.
Strain the peas.
Finish the soup
Mash the strained peas through a sieve back into the soup.
Return the soup to the heat.
Add sugar and stock to the soup.
Bring the soup to a boil.
Mix the flour into the butter. Add the flour-butter mixture to the boiling soup.
Season with salt and pepper.
Serve with diced toasted bread.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Break down into thick body and sweet, earthy flavour as they simmer and mash.
- Bacon or salt pork
- Adds savoury, smoky fat and salt flavour to the cooking liquid.
- Flour
- Thickens the soup by swelling in the hot liquid with the butter.
- Butter
- Carries the flour smoothly into the soup and adds richness.
- Sugar
- Adds a touch of sweetness that balances the savoury bacon and peas.
The step that matters
Adding the flour-butter mixture to the boiling soup. If the flour is dropped in as lumps or the soup is not kept moving, the starch clumps instead of dispersing and thickening evenly. Mixing the flour into the butter first coats the grains so they blend smoothly into the hot liquid.
Swap the peas
How well each one fits the dish's main ingredients (pork, sugar, flour, butter, pepper, bread):
- Chestnutfits better
- Almondfits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against pork, sugar, flour, butter, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
