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 thicken it as they break down during long simmering.
Salt pork
Adds fat and savory depth to the broth during long simmering.
Beef
Contributes meaty flavor and richness to the broth.
Onions
Add sweetness and savory aroma as they cook into the broth.
Lemon
Adds acidity that brightens the finished soup.

The step that matters

Boil for 3 to 4 hours, then strain. The beans must cook long enough to become fully soft and release their starch, so the soup thickens and the strained result is smooth rather than gritty.

Swap the lemon

How well each one fits the dish's main ingredients (beans, pork, beef, onion, carrot, wine, egg):
