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

What each ingredient does

Green peas
Provide the main body and flavour of the soup when mashed.
Milk
Forms the liquid base of the soup and gives it a creamy richness.
Flour
Thickens the soup, giving it body as it cooks with the butter.
Butter
Adds fat and richness, and helps the flour blend smoothly into the milk.

The step that matters

Adding the butter and flour to the boiling milk. Rubbing the butter and flour together first and adding them to boiling milk helps prevent lumps. Flour needs to be cooked in the hot liquid to thicken properly and lose its raw taste.

Swap the peas

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