Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for frying the vegetables, carrying flavour and helping them brown.
- Turnips
- Form the bulk of the soup, adding body and a mildly sweet, earthy flavour as they cook.
- Carrots
- Add sweetness and body to the soup as they soften in the broth.
- Potatoes
- Break down slightly as they cook, thickening the soup and giving it a fuller texture.
- Onions
- Build savoury depth when fried, and their sugars brown to add flavour to the base.
- Celery
- Adds aromatic, savoury flavour and body to the soup base.
The step that matters
Fry the vegetables until browned. Browning caramelises the natural sugars and proteins on the vegetables' surfaces, creating deeper flavour. Pale, under-fried vegetables give a flatter, blander soup, so colour them well before adding water.
Swap the onion
How well each one fits the dish's main ingredients (turnip, carrot, potato, celery, butter, pepper, bread):
