Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the fish, giving the soup its substance and flavour.
- Old hens
- Release gelatin and flavour into the broth, giving the consommé body and richness.
- Knuckle of veal
- Adds gelatin and depth to the broth, helping it set body and richness.
- Raw ham
- Contributes savoury, salty depth to the stock as it simmers.
The step that matters
Clarifying the consommé. If the broth is not skimmed and strained carefully, cloudy particles and fat stay suspended, leaving the consommé murky instead of clear and smooth.
Swap the onion
How well each one fits the dish's main ingredients (veal, ham, carrot, parsley, salmon, chervil, tarragon):
- Shallotfits better
- Chivefits better
- Leekfits better
- Onionthe original
