Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Creamed Salt Codfish
Ingredients
Directions
Prepare the fish
Cover the salt codfish with lukewarm water and let it stand until soft, then drain.
Make the sauce
Melt the butter in a pan, add the flour, and stir until well blended.
Gradually pour in the scalded milk and bring to a boil.
Add the softened fish and the beaten egg, stirring to combine.
Serve
Serve over slices of buttered toast or with baked potatoes.
For variety, mix in grated mild cheese.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt codfish
- Provides the main savoury flavour and the flaked texture of the dish.
- Flour
- Thickens the butter and milk into a smooth, creamy sauce.
- Milk
- Forms the liquid base of the sauce, giving it a creamy body.
- Egg
- Adds richness and helps bind the sauce as it thickens with the fish.
- Butter
- Adds fat and flavour, and forms the roux with the flour.
The step that matters
Adding the egg to the sauce. Egg proteins set with heat and can curdle or scramble if the sauce is boiling hot. Stir the beaten egg in gently and keep the heat low so the sauce stays smooth.
Swap the potato
How well each one fits the dish's main ingredients (butter, flour, milk, egg, cheese):
- Potatothe original
- Asparagusfits about as well
- Chivefits about as well
- Sweet potatofits less well
Fit is the average pairing score against butter, flour, milk, egg, cheese. Candidates are from the same food group and used in at least 100 recipes.
