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 ↓
Plain 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 eggs
Beat the yolks of the eggs until light and creamy.
Add the salt, pepper, and milk to the yolks and mix well.
Beat the egg whites until stiff but not dry.
Gently fold the egg whites into the yolk mixture.
Cook the omelette
Heat a frying pan and rub it with butter.
Pour the egg mixture into the pan and spread it evenly.
When the omelette is set, place it in a 400°F (200°C) oven.
Bake for a few minutes to dry the top slightly.
Fold the omelette and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped by beating give the omelette its light, airy structure, and the yolks set into a tender body.
- Milk
- Adds moisture so the eggs stay soft and tender rather than dry and rubbery.
- Butter
- Greases the pan so the omelette releases cleanly and adds a rich flavour.
The step that matters
Gently fold the egg whites into the yolk mixture. Egg whites hold air only while whipped. Heavy stirring knocks that air out, so the omelette turns flat and dense instead of light.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, milk, butter):
- Nutmegfits better
- Cinnamonfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
