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
Preheat a frying pan over brisk heat.
If necessary, clean the pan by heating it and wiping it with a coarse towel.
Make the batter
Separate the yolks and whites of the eggs, then beat the whites until stiff.
Beat the yolks, then mix in the pepper and salt.
Add butter and work it into a smooth, thick batter, then stir in the milk.
Gently fold in the beaten egg whites.
Cook and serve
Heat butter in the frying pan until hot, then pour in the egg mixture.
As the omelet cooks, loosen the edges with a thin-bladed knife.
Cook for 10 to 12 minutes, or transfer to a hot oven to brown the top.
To serve, place a hot dish upside down on the pan, then flip to transfer the omelet with the browned side up.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for lift, while the yolks enrich and set the omelet's structure.
- Milk or cream
- Adds moisture and a softer, more tender texture to the cooked omelet.
- Butter
- Adds richness and flavor, and browns the surface of the omelet in the pan.
The step that matters
Gently fold in the beaten egg whites. The whipped whites hold the air that gives the omelet its lift. Stirring or beating vigorously at this stage deflates the foam, leaving a dense, flat omelet.
