Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox tail
- Gives the soup its meaty flavour and body as it simmers for hours.
- Rice flour
- Thickens the soup slightly when boiled with the liquid.
- Turnip
- Adds earthy sweetness and body to the broth during long simmering.
- Carrot
- Adds gentle sweetness and colour to the broth.
- Onion
- Adds savoury depth and aroma to the broth.
The step that matters
Removing the scum from the surface. Scum is coagulated protein and impurities that rise as the liquid heats. Skimming it early keeps the broth clear and free of bitter or off flavours during the long simmer.
