Why it works: Chestnut and flour match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 517 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chestnut Sauce
Ingredients
Directions
Prepare the chestnuts
Peel and blanch the chestnuts.
Make the sauce
In a saucepan, combine the chestnuts and stock, adding the lemon peel.
Simmer until the chestnuts are soft, then pass through a sieve.
Stir in the salt and cream, and simmer gently until hot.
If the sauce is too thin, thicken with a little flour; if too thick, add more cream.
Serve very hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the main body and starchy, creamy texture of the sauce once softened and sieved.
- Cream
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Stock
- Provides the liquid that cooks the chestnuts and sets the sauce's consistency.
- Flour
- Thickens the sauce if it is too thin, adding body through starch.
The step that matters
Simmer until the chestnuts are soft, then pass through a sieve. Chestnuts must be fully softened before sieving, or the sauce will be grainy and lumpy. Gentle simmering keeps the sauce from scorching or breaking.
Swap the lemon

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