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, sweetness and colour of the soup.
- Butter
- Carries the flavour of the vegetables and adds richness during frying.
- Flour
- Thickens the soup so it has a smooth, body-rich texture.
- Stock
- Forms the liquid base and supplies savoury depth.
- Ham
- Adds salty, savoury flavour to the frying base.
- Onion
- Builds aromatic flavour as it softens and browns gently in butter.
The step that matters
Mix in the flour smoothly. Flour clumps if added to hot liquid or unevenly, leaving lumps. Stirring it into the fat and vegetables first, then adding liquid gradually, helps it disperse and thicken the soup evenly.
