Why it works: Celery and mustard are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,169 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ingredients
Directions
Prepare the beans
Soak beans overnight, drain and add cold water, rinse thoroughly.
Fry the onion in two tablespoons butter.
Add the onion to the beans with water and celery.
Cook slowly until the beans are soft, three or four hours, adding more water as it boils away.
Finish the soup
Rub through a strainer, add the seasonings and heat.
Heat the remaining butter in a saucepan, add the flour and the soup gradually; cook until well blended.
Cut lemon and eggs in thin slices and serve in soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup as they soften and break down when strained.
- Butter
- Carries the flavor of the onion and forms the base of the flour roux.
- Flour
- Cooked in butter, it thickens the soup and gives it a smooth body.
- Eggs
- Hard-boiled slices add richness and a mild, creamy contrast to the soup.
The step that matters
Cook the flour and butter until well blended. Cooking the flour in butter before adding the soup removes its raw taste and lets it thicken evenly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (beans, celery, pepper, butter, flour, tea, mustard):
