Why it works: Beans and pork are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 2,000 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Rinse and wash the beans thoroughly.
Cover with cold water and bring to a boil.
Add baking soda and boil for 5-10 minutes.
Drain the water and rinse the beans with fresh warm water.
Cook the soup
Add the pork, gash it four times, and cover with water.
Cook until the beans are soft, adding boiling water as needed.
Remove the pork, slice it, and brown in a skillet on both sides.
Return some of the beans to the skillet to brown with the pork drippings.
Optionally, strain the soup through a colander.
Add dumplings if desired.
Just before serving, stir in a cup of rich milk and let it boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the body of the soup and thicken it as they soften during cooking.
- Baking soda
- Raises the pH of the soaking water, helping the beans soften more quickly.
- Pork
- Adds savoury fat and flavour to the broth, and browned slices add roasted flavour.
- Rich milk
- Adds richness and creaminess to the soup just before serving.
The step that matters
Browning the beans with pork drippings. Browning in fat creates roasted, savoury flavours through the Maillard reaction. Returning some beans to the skillet adds depth, but they can scorch if left unattended over high heat.
Swap the beans
How well each one fits the dish's main ingredients (pork, milk):

- Soybeanfits better
- Cocoafits about as well
- Beansthe original
Fit is the average pairing score against pork, milk. Candidates are from the same food group and used in at least 100 recipes.
