Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vermicelli
- Thin pasta that gives the soup body and a soft, noodle-like bite.
- Lamb knuckle
- Bone and meat that release flavour and gelatin into the broth as they cook.
- Veal
- Adds meaty depth and body to the broth as it simmers.
- Onion
- Adds savoury, aromatic sweetness to the broth as it cooks.
The step that matters
Cooking the meat until well done. The lamb and veal must cook long enough for the connective tissue to soften and flavour to leave the meat. Undercooked meat yields a thin, bland broth and tough pieces. The record gives no time, so judge by tenderness.
Swap the onion
