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 ↓
Grandmother's Bean Soup
Ingredients
Directions
Cook the beans
Wash the white beans well and cook them in 1 quart of cold water.
When the water boils, pour it off and add another quart of cold water.
Add the piece of pork and salt to taste.
As the water boils away, add more water to keep the beans covered.
Cook until the beans mash easily.
Make the dough
Beat the eggs with 2 tablespoons of water and a pinch of salt.
Stir in flour until the mixture is very stiff.
Brown and serve
Remove two-thirds of the beans and place them in a pan.
Lay the piece of pork on top.
Sprinkle with salt and pepper.
Brown in the oven.
Season with a little pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White beans
- Form the body of the soup and thicken it as they break down during cooking.
- Pork
- Adds savory flavor and fat to the beans as they cook and brown.
- Eggs
- Bind the dough and give it structure once cooked.
- Flour
- Gives the dough its stiffness and structure so it holds together.
The step that matters
Cook the beans until they mash easily. Beans that stay firm will not break down to thicken the soup. Keeping them covered with water lets them cook evenly and soften fully.
Swap the beans
How well each one fits the dish's main ingredients (pork, egg, flour, pepper):
- Chestnutfits about as well
- Black-eyed peafits about as well
- Beansthe original
- Sesamefits about as well
Fit is the average pairing score against pork, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
