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

What each ingredient does

Cold cooked fish
Provides the main body and flavour of the soup as minced fish.
Milk
Forms the creamy base that gives the soup its smooth, rich texture.
Bread crumbs
Soaked in milk, they thicken the soup and add body.
Raw egg
Sets with heat and helps thicken and enrich the soup.
Butter
Adds fat for richness and a smooth mouthfeel.
Flour
Thickens the butter and milk mixture so the soup becomes smooth and creamy.

The step that matters

Adding the egg. Whipped raw egg must be incorporated into the hot mixture while stirring so it thickens gently without scrambling into lumps. Adding it too fast or to a boiling base can curdle it.

Swap the onion
