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 ↓
Omelet
Ingredients
Directions
Prepare the eggs
Separate the eggs and beat the whites until stiff.
In another bowl, mix the yolks with the milk, pepper, and salt.
Gently fold the beaten whites into the yolk mixture.
Cook and serve
Melt butter in a hot frying pan.
Pour the egg mixture into the pan and cook over medium heat.
When cooked, place a hot dish over the pan and flip to serve 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
- Whites trapped with air give the omelet its light, airy structure, while yolks set to a tender body.
- Milk
- Adds moisture so the omelet stays soft and tender rather than dry.
- Butter
- Fat for frying that helps the surface brown and adds richness.
The step that matters
Folding the whites into the yolk mixture. Folding gently keeps the air bubbles in the beaten whites intact. Stirring or deflating them makes the omelet dense and flat instead of light.
