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

What each ingredient does

Chestnuts
Provide the starchy, creamy body that thickens the soup when blended.
Milk or cream
Adds richness and a smoother, softer mouthfeel to the finished soup.
Onion
Builds a savory aromatic base as it softens in the simmering liquid.

The step that matters

Blend the mixture until smooth. Chestnuts are starchy, so thorough blending breaks down their cell walls and gives a smooth, velvety texture. Under-blending leaves grainy or lumpy pieces.

Swap the chestnut

How well each one fits the dish's main ingredients (onion, carrot, celery, pepper, milk):

  1. Beansfits better
  2. Chickpeafits about as well
  3. Lentilsfits about as well
  4. Chestnutthe original

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