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
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Soak the black beans overnight in water.
Drain and rinse the beans.
Cook the soup
In a pot, heat olive oil over medium heat.
Add onion and garlic, sauté until soft.
Add beans, water, salt, pepper, and bay leaf.
Bring to a boil, then reduce heat and simmer for 1.5 to 2 hours until beans are tender.
Remove bay leaf before serving.

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 and starch that thicken the soup as they cook tender.
- Onion
- Softens and sweetens as it sautés, building the soup's base flavour.
- Garlic
- Adds aroma that mellows and deepens during gentle sautéing in oil.
- Olive oil
- Carries the aromatics and adds richness and fat to the soup.
The step that matters
Simmer until the beans are tender. Dried beans must cook long enough to soften fully, since undercooked beans stay firm and starchy. Salt added before cooking can slow softening in some beans, so check tenderness rather than relying on time alone.
Swap the clove
How well each one fits the dish's main ingredients (beans, onion, garlic, pepper, olive):
- Cuminfits better
- Thymefits better
- Rosemaryfits better
- Clovethe original
Fit is the average pairing score against beans, onion, garlic, pepper, olive. Candidates are from the same food group and used in at least 100 recipes.
