Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Meat and bone release gelatin and flavour into the stock during long simmering.
- Knuckle of veal
- Bones add gelatin, giving the cooled stock body and a silky mouthfeel.
- Onion
- Halved onion contributes savoury, aromatic sweetness to the simmering broth.
- Carrot
- Halved carrot adds mild sweetness and aroma to the stock.
The step that matters
Skimming the scum on the first boil. Bringing the stock to a boil slowly and skimming the white scum keeps the broth clear; the brown scum is left in, as the record directs. Lifting off the foam removes coagulated proteins that would otherwise cloud the liquid.
