Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrot
- Adds natural sweetness and bulk, and gives the soup its orange colour.
- Potato
- Softens and breaks down when cooked, giving the soup a thicker, creamier body.
- Onion
- Contributes savoury aroma and a flavour base for the soup.
- Butter
- Adds fat for richer flavour and a smoother mouthfeel.
The step that matters
Cook until the vegetables are tender. Vegetables must be fully soft before sieving. Firm pieces resist breaking down, so the purée stays grainy and uneven.
