Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide the main body, colour and sweet flavour of the puree.
- Butter
- Adds fat and richness, giving a smoother mouthfeel and rounder flavour.
- Onions
- Build savoury aroma and sweetness as they soften in the butter.
- Celery
- Adds a fresh, aromatic background note to the soup.
- Broth
- Supplies the liquid that cooks the vegetables and sets the soup's body.
The step that matters
Cover and simmer until moisture is reduced, avoiding burning or browning.. Gentle heat draws out moisture and softens the vegetables. Too much heat scorches the sugars in the carrots and onions, causing bitter, burnt flavours that carry through the finished soup.
