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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Navy beans
- Provide the starch and body that thicken the soup as they break down.
- Baking soda
- Raises the pH of the soaking water, helping the beans soften more evenly.
- Fresh pork
- Adds savory flavour and fat to the broth as it simmers.
The step that matters
Parboil the beans for 20 minutes, then drain. Discarding the parboiling water removes compounds that cause bitterness and gas, and the beans need that clean start before the long simmer.
