Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cauliflower
- Forms the body of the soup and gives it its main flavour and thickness when blended.
- Butter
- Adds fat for a rich mouthfeel and helps soften the onion without browning it.
- Onion
- Adds savoury, aromatic sweetness as it softens in the butter.
- Cream
- Adds richness and a smooth, velvety texture to the finished soup.
The step that matters
Blend the mixture until smooth. Cauliflower must be cooked until fully tender before blending; firm pieces leave a grainy texture that no further heating will fix.
