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.
Butter
Adds fat and richness while softening the greens in the pan.
Eggs
Thicken the soup gently when beaten in and warmed, adding body and richness.
Cream
Adds fat and smoothness, mellowing the sharpness of the sorrel.

The step that matters

Mixing the eggs and cream into the soup. Eggs thicken when heated gently but curdle if the soup boils after they are added. Add them just before serving and keep the soup hot rather than boiling.

Swap the lettuce
