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

What each ingredient does

Vegetable marrow
Forms the bulk of the soup and provides its main body and mild flavour.
Butter
Adds richness and carries flavour as it coats the vegetables and onion.
Flour
Thickens the liquid as it simmers, giving the soup a smooth, body-rich texture.
Milk
Adds creaminess and a soft, rounded richness to the soup.

The step that matters

Simmering after adding the flour. Flour thickens only as it heats in liquid, and stirring it in without enough simmering can leave a floury taste or lumps. Keep stirring and simmer until the soup visibly thickens.

Swap the onion

How well each one fits the dish's main ingredients (butter, milk, flour, pepper):

  1. Potatofits better
  2. Capsicumfits better
  3. Chivefits better
  4. Onionthe original

Fit is the average pairing score against butter, milk, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
