Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable stock
- Forms the liquid base of the soup and carries the flavour of the vegetables.
- Milk
- Adds creaminess and softens the soup's flavour.
- Grated cheese
- Adds rich savoury flavour and body when stirred into the hot soup.
- Flour
- Thickens the soup when cooked in butter to form a roux.
- Butter
- Carries flavour for cooking the vegetables and the flour, adding richness.
- Carrots
- Contribute sweetness and colour as the main vegetable.
The step that matters
Thicken the soup with flour cooked in butter. Flour cooked in butter forms a roux that thickens the liquid smoothly. If the flour is added raw or not cooked, it can leave lumps or a raw floury taste.
Swap the mace
How well each one fits the dish's main ingredients (milk, carrot, cheese, onion, butter, flour):
- Parsleyfits better
- Thymefits better
- Celeryfits better
- Macethe original
Fit is the average pairing score against milk, carrot, cheese, onion, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
