Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Add sweetness and colour, and hold their shape as the soup simmers.
- Turnip
- Adds a mild, slightly peppery body to the broth as it softens.
- Cauliflower
- Softens into the broth, adding body and a mild, sweet flavour.
- Peas
- Add a fresh, sweet flavour and bright green colour near the end of cooking.
- Sorrel
- Adds a bright, lemony acidity that balances the sweet vegetables.
The step that matters
Adding the peas and asparagus at the end. Peas and asparagus turn dull and mushy with long cooking. Adding them only once the other vegetables are tender keeps their colour and texture.
