Ingredients
Directions
Prepare the vegetables
Cut the carrots, turnips, celery, leeks, and onions into thin shreds about 1 inch long.

Transfer the mixture to a soup pot.
Make the soup

Bring the soup to a boil.
Reduce the heat.
Skim off any scum and grease that rises to the surface.

Allow the soup to simmer until the vegetables are tender.
Taste and adjust seasoning before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness, colour and body as the main shredded vegetable.
- Turnips
- Add a mild, slightly peppery flavour and bulk to the soup.
- Leeks
- Contribute a gentle onion-like aroma and sweetness when softened in butter.
- Butter
- Carries fat-soluble flavour and softens the vegetables without browning them.
- Cabbage lettuces
- Add tender leafy texture and fresh flavour that cooks quickly in the hot broth.
The step that matters
Stir the vegetables only lightly in butter over low heat. Keeping the vegetables a very light colour avoids browning, which would add bitter, toasted flavours and change the clear, delicate character of the soup.
