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 ↓
Cheese Omelet
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the base
Mix flour and butter in a pan until thoroughly combined.
Add milk, salt, red pepper, cheese, and beaten egg yolks.
Cook and stir until smooth.
Fold and bake
Remove from heat and gently fold in the beaten egg whites.
Pour the mixture into a well-greased baking pan.
Bake in a moderate oven (350°F / 175°C) for 20 to 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam, they trap air that lifts the omelette as it bakes.
- Egg yolks
- Add richness and help set the custard-like base as it heats.
- Flour
- Cooked with butter, it thickens the milk mixture so it holds its body.
- Grated cheese
- Adds savoury flavour and fat, and melts into the base.
- Milk
- Provides moisture and softness to the base.
The step that matters
Fold in the egg whites gently. Whipped whites hold air that gives lift. Stirring or deflating them vigorously knocks out the foam, leaving a dense, flat omelette. Fold in gently, off the heat, so the air stays trapped.
