Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Chestnut Sauce
Ingredients
Directions
Prepare the chestnuts
Roast the chestnuts and remove the outer and inner skins.
Make the sauce
In a mortar, combine the chestnuts with butter and seasoning, and pound until smooth.
Gradually add the milk, cream, and stock, mixing well.
Transfer to a clean pan, bring to a boil, and serve.
For a smoother sauce, pass through a sieve before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Provide the starchy, sweet base that gives the sauce its body and flavor.
- Butter
- Adds richness and a smooth mouthfeel to the pounded chestnut paste.
- Milk
- Thins the chestnut paste into a pourable sauce while adding creaminess.
- Cream
- Adds fat for a silkier texture and a fuller, rounder finish.
- White stock
- Adds savory liquid that loosens the sauce and deepens its flavor.
The step that matters
Adding the liquids gradually. Pouring in the milk, cream, and stock slowly while mixing lets the chestnut starch and fat blend evenly, preventing lumps and a grainy or separated sauce.
Swap the chestnut
