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 flavour of the soup.
Milk
Adds creaminess and richness to the soup base.
Corn starch
Thickens the soup as it heats, giving it a smooth body.
Butter
Adds fat and a rounded, silky richness to the finished soup.

The step that matters

Stirring in the corn starch. Corn starch must be mixed with a little cold milk first so it does not clump. Once it reaches a simmer, the starch granules swell and thicken the soup; stir steadily until it is thick and glossy.

Swap the onion

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

  4. Onionthe original

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