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 ↓
Scalloped Codfish with Cheese
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fish
Soak the codfish in tepid water for 6 hours, then boil it.
Once cold, flake the fish with a fork and season with pepper.
Make the sauce
Heat the milk to a boil, then stir in the butter rolled in flour.
Mix the milk mixture with the flaked fish.
Bake and serve
Pour the mixture into a baking dish and top with grated cheese.
Bake in a 400°F (200°C) oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salted codfish
- Provides the main protein and flavour, with flakes that hold together in the baked dish.
- Milk
- Forms the liquid base of the sauce that moistens the fish.
- Butter
- Adds richness and fat, carrying flavour through the sauce.
- Prepared flour
- Thickens the milk into a smooth sauce that binds the fish together.
- Grated cheese
- Melts and browns on top, adding savoury flavour and a golden crust.
The step that matters
Soaking the codfish. Salted cod must be soaked long enough to remove most of its salt. Too little soaking leaves the fish harshly salty, and the salt cannot be removed by adding anything later.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
