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, earthy flavor of the soup when pressed into a purée.
- Butter or drippings
- Carry the onion's flavor and add richness to the base.
- Flour
- Thickens the soup as it cooks with the liquids.
- Milk
- Adds creaminess and moisture, making the soup smooth and rich.
- Onion
- Adds savory aromatic flavor to the base.
The step that matters
Cooking the flour into the chestnut mixture. Flour must cook for a few minutes with the fat and purée so its raw, pasty taste cooks off and it thickens evenly without lumps.
Swap the onion
How well each one fits the dish's main ingredients (chestnut, pepper, nutmeg, milk, butter, celery, flour):
- Parsnipfits better
- Arrowrootfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against chestnut, pepper, nutmeg, milk, butter, celery, flour. Candidates are from the same food group and used in at least 100 recipes.
