Why it works: Beans and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,733 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bean Soup
Ingredients
Directions
Wash the beans and place them in a pot with the cold water, salt pork, red pepper, and salt.
Bring to a boil and cook for two hours, or until the beans are well cooked.
Strain the soup through a colander and add milk or cream to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Soften during long cooking and break down slightly, giving the soup body and thickness.
- Salt pork
- Adds fat and savory flavor that carries through the broth as it simmers.
- Cold water
- Forms the broth, extracting flavor from the pork and softening the beans as it cooks.
The step that matters
Cooking until the beans are well cooked. Dried beans only become tender after sustained simmering. Stopping early leaves them firm and grainy, so check for a soft, fully yielding texture before straining.
Swap the beans
How well each one fits the dish's main ingredients (pork, pepper, milk):
- Soybeanfits about as well
- Beansthe original
- Peanutfits about as well
- Sesamefits less well
Fit is the average pairing score against pork, pepper, milk. Candidates are from the same food group and used in at least 100 recipes.
