What each ingredient does
- Calf's head with skin
- Skin and bone release gelatin, giving the broth body and a rich mouthfeel.
- Button mushrooms
- Add moisture and earthy savoury flavour as they simmer in the broth.
- Curry powder
- Adds warm, aromatic spice flavour to the broth.
- Lemon juice
- Adds acidity that brightens the rich broth just before serving.
The step that matters
Skim off any scum for 1 hour. Scum is coagulated protein and impurities rising from the simmering head. Removing it keeps the broth clear and stops off flavours from spoiling the soup.
