Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread crumbs
- Thicken the broth and give the soup body.
- Egg yolks
- Enrich the soup and add richness and smoothness when combined.
- Parmesan cheese
- Adds savory, salty flavor and richness to the soup.
- Butter
- Carries the flavor of the onions and ham and adds richness.
The step that matters
Stir in the egg yolks and Parmesan cheese. Egg yolks can curdle or scramble if the soup is too hot when they go in. Stirring them gently off the heat or over low heat keeps the soup smooth and silky.
Swap the mace
How well each one fits the dish's main ingredients (ham, onion, butter, bread, chicken, pepper, egg):
- Parsleyfits better
- Garlicfits better
