Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Black Bean Soup
Ingredients
Directions
Prepare the soup
Drain the soaked black beans and place them in a kettle.
Add cold water to cover the beans and include the chopped onion, fat meat, salt, garlic, and pepper.
Cook for about 3 hours, adding water or stock as it boils away, until the beans are soft enough to press through a sieve.
Serve
In a tureen, layer the sliced hard boiled eggs and lemon.
Pour the hot soup over the eggs and lemon in the tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Provide the main body of the soup, softening during long cooking until they can be pressed smooth.
- Fat meat
- Adds fat and savory flavor that carries through the long simmer into the broth.
- Hard boiled eggs
- Add a firm, mild contrast in texture when layered in the tureen under the hot soup.
- Lemon
- Adds acidity and brightness that cut through the rich, earthy soup.
The step that matters
Cook until the beans are soft enough to press through a sieve. Beans need a long, gentle simmer to soften fully. Adding water as it boils away keeps the beans submerged and cooking evenly, and undercooked beans will not press into a smooth soup.
Swap the clove
How well each one fits the dish's main ingredients (beans, onion, meat, garlic, pepper, egg, lemon):
