Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms a smooth paste that thickens the stock and gives the puree body.
Potatoes
Break down during cooking to add starch, creaminess and body to the puree.
Milk
Adds richness and a softer, creamier texture to the finished soup.
Carrots
Add sweetness, colour and body as they soften and blend into the puree.
Turnips
Contribute earthy flavour and body as they soften into the puree.
Onion
Builds savoury depth and aroma when lightly fried at the start.

The step that matters

Adding the flour paste to the pot. Flour lumps form if it is added dry or unmixed, so mixing it smoothly with water first lets it disperse evenly. Simmering the soup afterwards lets the starch fully cook, which removes the raw floury taste and thickens the liquid evenly.

Swap the onion

How well each one fits the dish's main ingredients (carrot, turnip, ham, flour, parsley, potato, milk):

  1. Parsnipfits better
  2. Leekfits better
  3. Beetrootfits better
  4. Onionthe original

Fit is the average pairing score against carrot, turnip, ham, flour, parsley, potato, milk. Candidates are from the same food group and used in at least 100 recipes.
