Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Hold their shape as firm rounds and add natural sweetness and colour to the broth.
- Peas
- Add sweetness and a tender texture that softens without falling apart.
- Asparagus points
- Add a fresh, grassy flavour and tender bite near the end of cooking.
- Sorrel
- Adds bright acidity that lifts the flavour of the broth.
- Cauliflower
- Contributes body and mild sweetness as it cooks into the broth.
The step that matters
Adding the peas and asparagus. Peas and asparagus cook quickly and turn dull grey-green and mushy if boiled too long. Adding them only once the other vegetables are tender keeps their colour, texture and flavour bright.
