Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sorrel
- Gives the soup its sharp, lemony acidity and bright green flavour.
- Egg yolks
- Thicken the soup into a smooth, creamy texture when gently heated.
- Cream or milk
- Adds richness and softens the sourness of the greens.
- Butter
- Adds fat and helps the vegetables soften gently while stewing.
- Leek
- Provides a mild onion-like sweetness and body to the base.
The step that matters
Mixing in the egg yolks and cream. If the soup boils after the egg yolks go in, they can scramble and turn grainy. Keeping it below boiling lets the yolks thicken it smoothly.
Swap the lettuce
