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

What each ingredient does

Chestnuts
Form the main body of the soup, giving it starch, body and a mildly sweet, nutty flavour.
Butter
Adds richness and carries flavour as the base for the roux.
All-purpose flour
Thickens the milk into a smooth sauce when cooked with the butter.
Milk
Forms the creamy liquid that the chestnut puree is blended into.

The step that matters

Gradually add the boiling milk to the roux. Adding hot liquid all at once to a flour and butter roux can cause lumps. Adding it gradually while stirring lets the starch disperse evenly so the sauce thickens smooth.

Swap the chestnut

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

  1. Almondfits better
  2. Chestnutthe original
  3. Milletfits about as well
  4. Walnutfits about as well

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