Ingredients
Directions
Prepare the vegetables
Cut the carrots, turnips, and other roots into thin slips, about 1 inch long.
Halve and slice the leeks, onions, celery, cabbage, and parsley.
Cook and combine
In a pot, fry or stew the root vegetables in a little butter.
In another pot, stew the other vegetables in a small amount of broth.
Combine all the vegetables and add the remaining broth.

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 root vegetable in the soup.
- Turnips
- Add a mild, slightly peppery flavour and firm texture that holds up to cooking.
- Leeks
- Contribute a gentle onion-like sweetness and aroma to the broth.
- Butter
- Adds fat and helps fry the root vegetables, carrying flavour and browning them gently.
- Broth
- Forms the liquid base that moistens and carries the vegetables into the finished soup.
The step that matters
Frying or stewing the root vegetables in butter. Cooking the roots gently in a little butter softens them evenly and builds flavour without browning them too much. Too much heat can scorch the butter and make the soup taste bitter, while too little leaves the roots firm and raw-tasting.
Swap the cabbage
How well each one fits the dish's main ingredients (carrot, turnip, leek, onion, celery, parsley, butter):
- Parsnipfits better
- Chivefits better
- Shallotfits better

Fit is the average pairing score against carrot, turnip, leek, onion, celery, parsley, butter. Candidates are from the same food group and used in at least 100 recipes.
