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

What each ingredient does

Sorrel
Provides the sharp, lemony acidity that defines the soup's flavour.
Egg yolks
Thicken the soup into a smooth, creamy texture when gently heated.
Cream or milk
Adds richness and softens the soup's flavour and mouthfeel.
Butter
Adds fat and carries flavour while the vegetables soften.
Leek
Contributes a mild onion-like sweetness as it stews.

The step that matters

Stirring in the egg yolks without boiling. Egg yolks thicken by gentle heat; if the soup boils after they are added, the proteins scramble and the soup turns grainy and curdled instead of smooth.

Swap the lettuce
