Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness, color and body to the soup's vegetable base.
- Butter
- Adds fat and richness, and helps the vegetables soften gently when melted.
- Leeks
- Contribute a mild onion flavor and aroma to the stock.
- Cabbage lettuces
- Add tender leafy texture and fresh vegetal flavor when added near the end.
The step that matters
Stir the vegetables lightly until just colored. Gentle cooking in butter softens the vegetables and builds flavor without browning too far. Over-browning turns the sugars bitter and darkens the clear stock, so the soup loses its delicate flavor and clarity.
Swap the onion
How well each one fits the dish's main ingredients (carrot, turnip, celery, leek, butter, sugar, cabbage):
- Parsnipfits better

- Lettucefits better
- Onionthe original
Fit is the average pairing score against carrot, turnip, celery, leek, butter, sugar, cabbage. Candidates are from the same food group and used in at least 100 recipes.
