Why it works: Peas and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,434 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
Green Pea Soup
Ingredients
Directions
Cook the peas
Combine shelled peas and water in a pot.
Cook until the peas are soft.
Skim out the peas.
Pass the peas through a colander back into the pot with the cooking water.
Boil for an additional 30 minutes.
Season with salt and pepper.
Thicken and finish
In a separate bowl, mix butter with rice flour (or all-purpose flour).
Stir the thickening mixture into the soup, ensuring it is well combined.
Cook until the soup reaches the consistency of good cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shelled peas
- Provide the main body, sweet flavor and green color of the soup.
- Butter
- Adds richness and fat, giving the soup a smoother mouthfeel.
- Rice flour
- Thickens the soup as its starch gelatinizes when heated in liquid.
The step that matters
Stir the thickening mixture into the soup. Flour clumps if added dry or left unblended, so mix it with butter first and stir it in thoroughly. Then keep cooking so the starch fully gelatinizes and the soup thickens smoothly.
Swap the peas
How well each one fits the dish's main ingredients (pepper, butter, rice):
- Black-eyed peafits better
- Beansfits better
- Almondfits better
- Peasthe original
Fit is the average pairing score against pepper, butter, rice. Candidates are from the same food group and used in at least 100 recipes.
