Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox cheek
- Provides rich meat and gelatin that give the soup body and a silky mouthfeel after long cooking.
- Brown flour or roux
- Thickens the liquid by starch gelatinization, giving the soup a fuller, smoother body.
- Vegetables
- Fried first in fat to build caramelized, savoury flavour that seasons the broth.
The step that matters
Skim the surface after boiling. Bringing the liquid to a boil releases coagulated proteins and fat foam to the surface. Removing them keeps the broth clear and free of greasy, bitter notes during the long gentle simmer.
