Why it works: Chestnut and pepper work together. They rank in the top 13% of all ingredient pairs, and cooks put them together in 826 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Chestnut Soup
Ingredients
Directions
Prepare the chestnuts
Remove the outer rind from the chestnuts and soak them in warm water until they are too hot to touch.
Peel the chestnuts quickly and place them in cold water.
Weigh the chestnuts and use ¾ pound for each quart of soup.
Cook and purée
Cover the chestnuts with stock and simmer gently for about 45 minutes, until tender.
Drain the chestnuts and mash them smoothly or pound them with a strong spoon.
Pass the mixture through a fine sieve and gradually mix in the appropriate amount of stock.
Season and finish
Season the soup with mace, cayenne, and salt, stirring often until it boils.
If desired, stir in up to ¾ pint of rich cream to enhance the flavor.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spanish chestnuts
- Provide the starchy base that thickens the soup and gives it a smooth, earthy body.
- Stock
- Supplies the liquid that cooks the chestnuts and carries the soup's flavor.
- Rich cream
- Adds fat and richness, giving the soup a silkier mouthfeel.
The step that matters
Sieving the purée. Chestnut purée can be grainy or lumpy if not passed through a fine sieve. Sieving breaks down remaining fibres and pieces, producing the smooth texture the soup depends on.
Swap the mace
How well each one fits the dish's main ingredients (chestnut, pepper, cream):
- Nutmegfits better
- Tarragonfits better
- Sagefits better
- Macethe original
Fit is the average pairing score against chestnut, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
