Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the soup and carries the cheese and flavor.
- Flour
- Thickens the milk as it heats, giving the soup body.
- Parmesan cheese
- Adds savory, salty flavor and richness to the soup.
- Egg yolks
- Enrich the soup and add body and smoothness when stirred in.
- Olive oil
- Adds fat that blends with the flour and carries flavor.
The step that matters
Adding the egg yolks. Egg yolks can scramble if the soup is too hot when they go in. Adding them off the heat or at low heat, while stirring, keeps the soup smooth and thickened.
Swap the mace
How well each one fits the dish's main ingredients (milk, onion, carrot, flour, olive, parmesan cheese, egg):
- Parsleyfits better
- Garlicfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against milk, onion, carrot, flour, olive, parmesan cheese, egg. Candidates are from the same food group and used in at least 100 recipes.
