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 Omelet
Ingredients
Directions
Prepare the batter
Beat the egg whites until stiff and the yolks until smooth.
Add the milk, cornstarch, baking powder, salt, and pepper to the yolks and mix well.
Gently fold in the beaten egg whites.
Cook and serve
Heat a good amount of butter in a frying pan over medium heat until it hisses.
Pour the egg mixture into the pan and cook for about 10 minutes without stirring.
As the omelet sets, use a broad knife to prevent it from burning.
When nicely browned, roll the omelet onto a hot dish 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 trap air for lift while yolks add richness and set the structure of the omelet.
- Milk
- Adds moisture and tenderness to the omelet as it cooks.
- Cornstarch
- Helps the omelet stay tender and soft by thickening the egg mixture.
- Baking powder
- Releases gas during cooking to make the omelet rise and lighten.
- Butter
- Adds richness and helps brown the surface of the omelet in the pan.
The step that matters
Cooking the omelet without stirring. Stirring breaks the forming set of egg proteins and deflates the air from the folded whites. Letting it set undisturbed keeps the omelet light and gives it an even, browned base.
