Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb knuckle
- Releases gelatin and meaty flavor into the broth, giving it body and richness.
- Veal
- Adds savory meat flavor and body to the broth alongside the lamb.
- Vermicelli
- Thin pasta that softens in the hot broth and gives the soup its main starch.
- Onion
- Adds aromatic sweetness and depth as it cooks into the broth.
- Worcestershire sauce
- Adds tangy, savory depth that rounds out the broth's flavor.
The step that matters
Boil the vermicelli separately until tender. Pasta keeps absorbing liquid and turns mushy if left sitting in hot broth. Cooking it in its own pot and adding it at the end keeps the noodles firm and the broth clear.
Swap the onion
How well each one fits the dish's main ingredients (lamb, veal, pepper, sauce):
- Capsicumfits better

Fit is the average pairing score against lamb, veal, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
