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 ↓
Making Omelets
Ingredients
Directions
Prepare
Beat the yolks of the eggs lightly, about twelve beats.
Add the milk, salt, pepper, and flour if using.
Beat the egg whites to a stiff froth.
Fold the beaten whites into the yolk mixture.
Cook
Heat a dry frying pan.
Add a small amount of fat and let it simmer, then pour out the fat and wipe the pan dry.
Add the butter or oil.
Pour in the omelet mixture.
Let the mixture bubble and rise, lifting the edges occasionally with a thin knife to prevent burning.
Serve
When the underside is firm, fold the omelet.
Slide the folded omelet onto a hot platter.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lift while yolks set and add richness and structure.
- Milk
- Adds moisture, keeping the cooked eggs soft and tender rather than dry.
- Flour
- Adds body so the omelet holds its shape when folded.
- Butter or oil
- Fat keeps the omelet from sticking and promotes gentle golden browning.
The step that matters
Fold the beaten whites into the yolk mixture. Whites hold air that gives the omelet its lift. Stirring vigorously collapses that foam, leaving the omelet flat and dense.
