Why it works: Milk and bread are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 11,466 recipes. Both carry 2-undecenal, which smells sweet. The science ↓
White Bean Soup
Ingredients
Directions
Prepare the beans
Put the white beans in 1 quart of cold water and boil for 5 minutes.
Drain the boiling water and place the beans in cold water until the skins burst.
Cook the soup
Combine the beans with 2 quarts of cold water and the blanched pork, then simmer until the beans are very soft.
Add salt and pepper to taste.
Once the beans are soft, strain them through a sieve and return to the stove.
Add 1 pint of milk and let it boil before removing from heat.
Serve
Serve with bread cut into dice and browned in the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Provide the main body and thickness of the soup as they soften and break down.
- Milk
- Adds richness and a smoother, creamier texture to the soup.
- Blanched pork
- Adds savoury flavour and richness to the cooking liquid.
The step that matters
Simmer until the beans are very soft. Beans must be fully tender before straining; under-cooked beans stay firm and grainy, so the soup will not pass smoothly through the sieve.
Swap the beans
How well each one fits the dish's main ingredients (pork, pepper, milk, bread):
- Beansthe original
- Lima beansfits about as well
- Peasfits about as well
- Peanutfits about as well
Fit is the average pairing score against pork, pepper, milk, bread. Candidates are from the same food group and used in at least 100 recipes.
