Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Neck mutton
- Gives the soup its rich meaty flavour as it cooks slowly in the water.
- Potatoes
- Break down slightly as they cook, adding body and thickening the broth.
- Rice
- Absorbs liquid and swells during simmering, thickening the soup further.
- Onions
- Add savoury sweetness and aroma as they soften in the broth.
- Carrot
- Adds natural sweetness and colour to the soup.
The step that matters
Skimming the foam. Foam that rises as the mixture first heats contains impurities and fat that cloud the broth and taste unpleasant. Removing it early, and skimming again before serving, keeps the soup clear and clean-flavoured.
