Why it works: Chestnut and walnut share more aroma than cooks usually use. They rank in the top 6% of all ingredient pairs, and cooks put them together in 60 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Puree of Chestnuts
Ingredients
Directions
Prepare the chestnuts
Remove the outer brown skin from the chestnuts.
Boil the chestnuts until the inner skin comes off easily.
Remove the inner skin and place the chestnuts in a saucepan.
Add enough white stock to cover the chestnuts and boil gently until soft.
Press the hot chestnuts through a wire sieve to make a pulp.
Finish and serve
In a saucepan, combine the chestnut pulp, butter, cream or milk, stock, salt, pepper, and sugar.
Stir over heat until hot and serve in the center of a dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the starchy, floury base that becomes a smooth, thick purée when pressed.
- Butter
- Adds richness and a silky mouthfeel to the purée.
- Cream or milk
- Adds moisture and creaminess, loosening the purée and softening its texture.
- White stock
- Softens the chestnuts during cooking and adds liquid to the finished purée.
The step that matters
Boil the chestnuts gently until soft. Chestnuts must be fully softened so they press into a smooth pulp. Undercooked chestnuts stay grainy and clog the sieve, while vigorous boiling can break them up unevenly.
Swap the walnut
How well each one fits the dish's main ingredients (chestnut, butter, cream, pepper, sugar):
- Almondfits better
- Pistachiofits better
- Cashew nutfits better
- Walnutthe original
Fit is the average pairing score against chestnut, butter, cream, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes.
