Why it works: Beans and olive match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 3,470 recipes. Both carry trans,trans-2,4-nonadienal, which smells fatty, green. The science ↓
Cream of Beans
Ingredients
Directions
Prepare the beans
Boil the beans until soft and mushy.
Mash the beans through a sieve.
Make the soup
Add the milk, egg, olive oil, salt, and cayenne pepper to the mashed beans.
Return the mixture to the heat and bring to a boil.
Thicken and finish
For a thicker soup, retain 2 tablespoons of olive oil.
In a saucepan, brown the retained olive oil with the flour.
Smooth the flour mixture with part of the soup, then combine it all back into the pot.
Allow the soup to boil together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Mashed into a soft purée that gives the soup its body and bulk.
- Milk
- Forms the creamy liquid base of the soup.
- Egg
- Adds richness and some body to the soup as it heats.
- Olive oil
- Adds fat for richness and, when browned with flour, helps build the thickener.
- Flour
- Its starch thickens the soup once cooked in hot fat and boiled with the liquid.
The step that matters
Smoothing the browned flour mixture with soup. Flour added directly to hot liquid clumps. Cooking it in oil first coats each grain, and blending it smooth with some soup before returning it to the pot lets the starch disperse evenly. Boiling then swells the starch and thickens the soup.

Fit is the average pairing score against milk, egg, olive, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
