Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lentils
Break down during long boiling, releasing starch that thickens the soup into a body.
Meat gravy
Adds savory depth and a meaty flavor to the soup.
Milk or cream
Adds richness and softens the flavor, giving a smoother mouthfeel.

The step that matters

Boil for 4 hours. Lentils need a long, sustained simmer to soften fully and break down. This releases their starch, which thickens the soup. If the boil is cut short, the lentils stay firm and the puree turns grainy and thin.

Swap the lentils

How well each one fits the dish's main ingredients (meat, milk):

  1. Cocoafits better
  2. Peanutfits better
  3. Pecansfits better
  4. Lentilsthe original

Fit is the average pairing score against meat, milk. Candidates are from the same food group and used in at least 100 recipes.
