Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to cook the vegetables gently in fat, carrying flavour and giving body to the broth.
- Onions
- Sweeten and build the savoury base as they soften in the butter.
- Egg yolks
- Enrich and thicken the soup when beaten in at the end, giving it a silky texture.
- Vinegar
- Adds a sharp acidity that brightens the mild, cooked vegetable flavours.
The step that matters
Beating in the egg yolks and vinegar. Egg yolks can curdle or scramble if the soup is boiling when they are added. Adding them just before serving, off the boil, keeps the soup smooth and thickened.
