What each ingredient does
- Ox-tail
- Its collagen breaks down during long simmering, giving the broth a richer, more body-filled texture.
- Potatoes
- Their starch softens and slightly thickens the broth while adding substance to the soup.
- Onions
- As they soften in the hot broth, they add sweetness and a savoury aroma that builds the flavour base.
The step that matters
Skim off all the fat from the broth. Fat from the meat rises and collects on the surface during boiling. Removing it before adding the vegetables keeps the soup from tasting greasy and gives a cleaner, clearer broth.
