Chestnut Soup, or Purée of Chestnuts

Ingredients

Directions

Prepare the chestnuts

  1. Peel the chestnuts. To make this easier, place them in a saucepan with butter over low heat, stirring occasionally until the husks come off easily.

  2. Add enough stock or water to the peeled chestnuts and boil gently until tender.

  3. Pound the chestnuts in a mortar and strain through a wire sieve.

Finish and serve

  1. For a brown soup, add a little brown roux and burnt sugar; for a white soup, add white roux and cream.

  2. Season with pepper, coarse sea salt, and enough butter to make the purée smooth. Add a little powdered sugar.

  3. 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 main body of the soup, becoming a thick, starchy purée when pounded and strained.
Butter
Adds richness and a smooth, silky mouthfeel to the finished purée.
Roux
Thickens the soup and, depending on type, adds color and body.
Cream
Adds richness and a smoother, milder texture in the white version.

The step that matters

Straining the purée until smooth. Chestnuts are starchy and fibrous, so pounding alone leaves grainy bits. Pressing the mash through a sieve removes the fibers and gives the silky texture the soup depends on.

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.
