Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Knuckle of veal
- Gives the broth body and rich, gelatinous flavour during the long simmer.
- Old hens
- Adds deep meaty flavour and richness to the consomme base.
- Raw ham
- Contributes savoury, salty depth to the stock.
- Salmon
- Provides the main fish body and delicate flavour to the soup.
- Chablis or sauterne
- Adds acidity and wine aroma that brightens the rich broth and fish.
The step that matters
Clarify the strained liquid. Clarifying removes cloudy particles so the consomme stays clear. Skipping or rushing it leaves a murky soup, and the broth must be cleared before the fish is added.
Swap the onion
