Make the soup
In a large pot, combine the giblets, gravy beef, mutton, veal bone, ox-tail, onions, sweet herbs, white pepper, and coarse sea salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Goose or duck giblets
- Provide the main poultry flavor and tender meat for the soup.
- Gravy beef
- Adds rich, savory beef flavor and body to the broth.
- Onions
- Contribute sweetness and aromatic depth as they cook down into the broth.
- Ox-tail
- Releases collagen during long simmering, giving the broth body and a silky richness.
The step that matters
Cook until the giblets are tender. Giblets toughen if undercooked and can turn rubbery if boiled hard. A gentle simmer lets connective tissue break down slowly while keeping the meat tender and the broth clear.

Fit is the average pairing score against beef, mutton, onion. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
