Why it works: Milk and butter 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 Codfish
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Shred the codfish into very small pieces and wash thoroughly in cold water.
Make the custard
Pour milk or cream over the codfish and bring to a boil.
Thicken the mixture with a little flour.
Add a good-sized piece of butter and remove from heat.
Stir in two well-beaten eggs.
Bake and serve
Transfer the mixture to a baking dish and cover with a layer of mashed potatoes.
Bake in the oven at 400°F (200°C) until golden brown.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Codfish
- Forms the main body of the dish, providing the savory flavor and flaky texture.
- Milk or cream
- Creates the moist, saucy base that cooks into a creamy mixture.
- Flour
- Thickens the liquid so the mixture holds together rather than running.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
- Eggs
- Set when heated, binding the mixture and giving it a custard-like structure.
- Mashed potatoes
- Forms a top layer that browns in the oven for color and a contrasting texture.
The step that matters
Stirring in the eggs off the heat. Eggs are removed from the heat before they are added so they thicken gently. If the mixture is still boiling, the proteins can scramble and turn grainy instead of smooth.
Swap the potato
How well each one fits the dish's main ingredients (milk, flour, butter, egg):
- Chivefits about as well
- Potatothe original
- Leekfits about as well
- Asparagusfits about as well
Fit is the average pairing score against milk, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
