Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold cooked fish
- Forms the main body of the soup and gives it its flavour.
- Milk
- Provides the creamy base and soft, smooth texture of the soup.
- Bread crumbs
- Soaked in milk, they thicken the mixture and give it body.
- Raw egg
- Adds richness and helps bind and thicken the soup when stirred in.
- Butter
- Adds fat and richness, smoothing the thickening mixture with flour.
- All-purpose flour
- Mixed with butter to help thicken the milk and give a smooth consistency.
The step that matters
Beat in the whipped raw egg, then pour the boiling fish and onion water into the mixture while stirring continuously.. Egg proteins set when heated, so adding the egg and boiling liquid while stirring constantly keeps the mixture smooth rather than curdled or lumpy.
Swap the onion
How well each one fits the dish's main ingredients (fish, milk, butter, flour, bread, egg):
- Asparagusfits better

- Leekfits better
- Onionthe original
Fit is the average pairing score against fish, milk, butter, flour, bread, egg. Candidates are from the same food group and used in at least 100 recipes.
