Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the broth into a silky, lightly set soup when gently heated with the cream.
- Cream or milk
- Adds richness and a smooth, mellow body to the thickened broth.
- Chicken broth
- Forms the base liquid that carries the flavour of the whole soup.
- Bread crumbs
- Bind the chopped chicken into tender forcemeat balls that hold together in the broth.
- Lemon juice
- Adds acidity that brightens the soup and balances the richness of the eggs and cream.
The step that matters
Thickening the broth with egg and cream. Eggs thicken through gentle heat; if the broth boils after adding the egg mixture, the eggs can scramble and curdle, leaving the soup grainy.
