Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Hold their shape and add sweetness and colour to the soup.
- Turnips
- Add firm texture and a mild, slightly sharp flavour to the vegetables.
- Celery
- Adds aroma and a crisp, fibrous texture to the soup.
- Onions
- Build savoury depth and aroma as they soften in the stock.
- Leeks
- Add a mild onion flavour and soft texture to the soup.
The step that matters
Timing the vegetables in the boiling stock. Dense root vegetables like carrots and turnips need to cook first so they become tender, while later vegetables added after 10 minutes stay firmer. Adding everything at once leaves some pieces mushy and others hard.
