Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lamb knuckle
- Gives the broth its meaty body and rich savory flavor as it simmers.
- Veal
- Adds gelatin and depth to the broth, giving it a fuller mouthfeel.
- Vermicelli
- Provides the starchy noodles that soften and thicken the soup slightly as they cook.
- Onion
- Contributes sweetness and aromatic depth to the seasoned broth.
- Worcestershire sauce
- Adds acidity and savory, umami-rich flavor to the broth.
The step that matters
Boil the vermicelli separately until tender. Cooking noodles directly in the broth releases starch that clouds the soup and makes it gummy. Boiling them in a separate pot and adding them later keeps the broth clear and the noodles at the right texture.
Swap the onion
How well each one fits the dish's main ingredients (lamb, veal, pepper, sauce):
- Capsicumfits better
