Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides meat flavor and body to the broth as it simmers.
- Veal shanks
- Add gelatin-rich collagen that gives the broth a fuller, silkier body.
- Egg yolks
- Thicken the soup and give it a smooth, rich texture when stirred in.
- Onion
- Adds savory depth and aroma to the broth.
- Asparagus
- Contributes vegetable flavor and a delicate, grassy aroma.
The step that matters
Thicken the soup with the egg yolks. Egg yolks can scramble if the soup is too hot when they are added. Temper them by whisking in a little hot broth first, then stir them back in over low heat without boiling so the soup thickens smoothly.
Swap the onion
How well each one fits the dish's main ingredients (veal, parsley, asparagus, egg):
- Shallotfits better
- Leekfits better
