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 ↓
Codfish Omelette
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare the codfish
Soak the salt codfish in water overnight to cover.
Press the codfish dry and chop it very fine.
Make the mixture
In a saucepan, bring the milk to a boil and stir in the chopped codfish.
In a separate bowl, mix the flour with butter until smooth, then stir the mixture into the milk.
Add the beaten eggs and mix thoroughly.
Bake
Pour the mixture into a buttered dish and bake in a hot oven (400°F / 200°C) until it rises and browns on top.

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 savory flavor and firm, flaky texture of the omelette.
- Milk
- Forms the liquid base that cooks into a soft, custard-like body.
- Flour
- Thickens the milk mixture so it holds together rather than running loose.
- Butter
- Adds richness and helps the flour blend smoothly, while greasing the dish.
- Eggs
- Set when baked, giving structure and helping the dish rise and brown.
The step that matters
Pressing the codfish dry. Excess water left in the salted fish would thin the mixture and make the baked dish soggy, so the fish should be well drained before chopping and adding.
