Chestnut Soup, or Puree of Chestnuts

Ingredients

Directions

Prepare the chestnuts

  1. Peel the chestnuts.

  2. Place them in a saucepan with butter over low heat, stirring occasionally until the husks come off easily.

  3. Add enough stock or water to cover the chestnuts and boil gently until tender.

  4. Pound the chestnuts in a mortar.

  5. Strain through a wire sieve.

Finish and serve

  1. For a brown soup, add a little brown roux and Parisian essence.

  2. For a white soup, add white roux and cream.

  3. Season with pepper, salt, and sufficient butter to achieve a soft taste.

  4. Add a little powdered sugar.

  5. Serve with fried and toasted bread.

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

What each ingredient does

Chestnuts
Form the body of the soup, giving it starch, thickness and a sweet, nutty flavour.
Butter
Adds richness and a soft, smooth mouthfeel to the soup.
Roux
Thickens the soup, giving it body when added to the strained purée.

The step that matters

Straining through a wire sieve. Chestnuts cooked until tender still hold fibrous, grainy bits; pressing the purée through a fine sieve removes them, so the soup turns out smooth rather than gritty.

Swap the chestnut

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

  1. Chestnutthe original
  2. Almondfits about as well
  3. Lima beansfits about as well
  4. Beansfits about as well

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