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 (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the codfish
Soak the salt codfish overnight in just enough water to cover.
Press dry and chop the codfish very fine.
Make the batter
In a saucepan, heat the milk until it comes to a boil.
Stir in the flour and butter until well combined.
Add the beaten eggs and mix thoroughly.
Bake
Pour the mixture into a buttered dish.
Bake in a hot oven at 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 savoury flavour and substance of the omelette.
- Eggs
- Set when heated, giving the omelette its structure and rise.
- Milk
- Adds moisture and softness to the mixture.
- Flour
- Thickens the milk mixture so it holds together after baking.
- Butter
- Adds richness and fat, helping the top brown.
The step that matters
Bake until it rises and browns on top. Eggs set as they heat, and the proteins trap air so the dish puffs. Taking it out too early leaves it flat and wet in the centre, while baking too long dries it out and makes it tough.
