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

What each ingredient does

Carrot puree
Forms the bulk of the soup and gives it its main flavor and sweetness.
Sweet milk
Provides the liquid base and makes the soup creamy and smooth.
Butter
Adds richness and fat, carrying flavor and giving a smooth mouthfeel.
Flour
Thickens the soup as its starch swells in the hot liquid.

The step that matters

Cook and stir until it boils. Flour only thickens fully when its starch swells in hot liquid, so the mixture must reach a boil. Constant stirring keeps the flour dispersed, preventing lumps and scorching on the bottom of the pan.

Swap the carrot

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

  1. Potatofits better
  2. Capsicumfits better
  3. Chivefits about as well
  4. Carrotthe original

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