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

What each ingredient does

Peas
Provide the main body and green flavour of the soup once mashed and strained.
Milk
Forms the creamy liquid base that gives the soup its smooth, rich body.
Butter and flour
Together form a roux that thickens the milk into a smooth, velvety soup.
Cream
Adds richness and a silky mouthfeel through its fat content.
Beef extract
Adds concentrated savoury depth to the pea soup.

The step that matters

Adding the hot milk to the butter-flour mixture. Pouring hot milk in gradually while stirring constantly keeps the flour dispersed, so the roux thickens smoothly instead of forming lumps.
