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 ↓
Scalloped Fish
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Remove bones and skin from the fish, and break it into bits about 1 inch long and half the thickness of your little finger.
Make the dressing
Scald 1 pint of milk over boiling water.
Mix the flour with the remaining milk and add it to the scalded milk.
Cook until thicker than boiled custard.
Remove from heat and immediately whisk in the beaten egg yolks, butter, cayenne, salt, and half of the grated nutmeg.
Assemble and bake
Butter a baking dish.
Layer the dressing, then the fish, repeating until the dish is full, finishing with a layer of dressing.
Cover with grated bread.
Sprinkle the remaining nutmeg on top.
Bake for 45 minutes in a moderate oven (350°F or 175°C).
Avoid too much heat to prevent drying out the fish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, providing the flaky filling layers.
- Egg yolks
- Thicken the milk dressing as they set and add richness to the custard-like sauce.
- Flour
- Thickens the milk so the dressing holds its body between the fish layers.
- Butter
- Adds richness and fat that keeps the dressing smooth and moist.
- Milk
- Forms the liquid base of the dressing that thickens into a custard-like sauce.
The step that matters
Cook the dressing and keep the oven moderate. Cooking the dressing only until it is thicker than boiled custard, then baking gently, keeps the egg yolks from curdling and the fish from drying out.
Swap the nutmeg
How well each one fits the dish's main ingredients (fish, butter, flour, milk, pepper, egg):
- Nutmegthe original
- Parsleyfits about as well
- Cinnamonfits about as well
- Capersfits less well
Fit is the average pairing score against fish, butter, flour, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
