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 and give it its earthy flavour and thickness once strained.
Beef bones or lean salt pork
Add savoury depth and richness to the cooking liquid as it simmers for hours.
Lemon juice
Adds acidity that brightens the soup and balances its rich, earthy flavour.

The step that matters

Boil for 3 to 4 hours. A long, steady simmer is needed to soften the beans fully and draw flavour from the bones or pork. A hard rolling boil can break the beans apart and cloud the broth, so keep it at a gentle simmer.

Swap the clove

How well each one fits the dish's main ingredients (beans, beef, pepper, lemon, egg, bread):
