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 ↓
A Very Delicate Omelette
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Beat the egg whites until stiff.
Beat the yolks until well mixed.
Melt the butter in the warm milk.
Mix the flour with a little of the milk to form a paste.
Add the paste to the milk mixture.
Stir in the salt and pepper.
Combine the milk mixture with the egg yolks.
If desired, add chopped onion, parsley, ham, or dried beef.
Bake and serve
Gently fold in the beaten egg whites.
Pour the mixture into a deep, round dish or tin cake pan.
Bake for about 15 minutes until cooked through, but do not let it brown too quickly.
Serve immediately from the baking pan with butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites are beaten to add lift and airy structure, while yolks enrich the custard-like body.
- Milk
- Provides the liquid base that sets into a tender, moist custard when heated.
- Flour
- Thickens the milk mixture so the omelette holds together rather than weeping liquid.
- Butter
- Adds richness and flavour to the milk base and to the finished dish.
The step that matters
Folding in the egg whites. Stiffly beaten whites trap air that gives the omelette its rise. Folding gently keeps that air in; stirring vigorously deflates the foam and leaves a dense result.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (egg, milk, butter, flour, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
