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
- Small white beans
- Provide the bulk and body of the soup as their starch softens during soaking and boiling.
- Milk
- Adds creaminess and mild richness to the finished soup.
The step that matters
Add the milk just before serving. Milk can scorch on the bottom of the pot and separate or curdle if it is kept boiling for long. Adding it at the end, over gentle heat, keeps it smooth and fresh-tasting.
