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

What each ingredient does

Fresh green peas
Provide the main body and flavour of the soup once mashed.
Milk
Forms the liquid base and gives the soup a creamy, smooth body.
Flour
Thickens the milk as it heats, giving the soup a fuller texture.
Butter
Adds richness and fat, smoothing the flour and adding flavour.

The step that matters

Adding the butter‑flour mixture to the boiling milk. Flour clumps if dropped into hot liquid unevenly. Rubbing it smooth with butter first and adding it while the milk is boiling and stirred helps it disperse and thicken evenly without lumps.

Swap the peas
