Why it works: Onion and celery are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
A Dish of Chestnuts
Ingredients
Directions
Prepare the chestnuts
Remove the outer rind from the chestnuts and cover them with boiling water.
As the water cools, slip the brown skin from the nuts and drop them in cold water.
Cook the chestnuts in sufficient water to cover until quite tender, adding the onion, celery, mace, and bay leaf while cooking.
Make the soup
Mash the cooked chestnuts through a puree sieve and return to the fire.
Add the white stock, salt, paprika, and hot milk to the chestnut puree.
When the soup boils, draw it to the back of the stove and add a liaison of the beaten egg yolks and sweet cream.

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, becoming a smooth puree that thickens it.
- Egg yolks
- Enrich and thicken the soup when added as a liaison without boiling.
- Sweet cream
- Adds richness and a silky texture to the finished soup.
- Hot milk
- Adds creaminess and moisture, mellowing the soup's body.
- White stock
- Provides the liquid base that carries the chestnut flavour.
The step that matters
Adding the egg yolk and cream liaison. If the soup is boiling when the yolks go in, they can scramble and curdle. Drawing it off the heat first lets the yolks thicken it smoothly.
Swap the mace
How well each one fits the dish's main ingredients (chestnut, onion, celery, milk, egg, cream):
- Nutmegfits better
- Tarragonfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against chestnut, onion, celery, milk, egg, cream. Candidates are from the same food group and used in at least 100 recipes.
