Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Form the main body of the soup and give it its sweet flavour and colour.
- Flour
- Thickens the soup with the milk, giving it a smoother, heavier body.
- Milk
- Adds richness and softness, rounding out the flavour and texture of the soup.
- Margarine
- Fat that softens the onion and carrots and carries flavour at the start of cooking.
The step that matters
Blending the flour with the milk before adding it to the soup. Flour added dry or unmixed clumps and stays lumpy. Blending it smoothly with cold milk first lets the starch disperse, so it thickens evenly when the mixture is returned to the hot soup and brought to a boil.
Swap the onion

- Shallotfits better
- Onionthe original
Fit is the average pairing score against carrot, ham, parsley, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
