Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when simmered and blended to give the soup its thick, creamy body.
- Onions
- Soften and turn sweet during gentle cooking, adding depth to the soup's flavour.
- Butter
- Carries the onions and mushrooms gently and adds richness to the soup.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the blended soup.
- Mushrooms
- Release moisture and savoury flavour as they cook down with the onions.
The step that matters
Blending the soup until smooth. Blending in batches and running the processor long enough breaks the cooked potato fully into the liquid. Undercooked or under-blended potato leaves the soup grainy instead of velvety.
