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 and Fancy Omelet
Ingredients
Directions
Prepare the batter
Beat the yolks of two eggs until light-colored and thick.
Add milk, salt, and pepper to the yolks and mix well.
Beat the whites of two eggs until stiff and dry.
Gently fold the beaten whites into the yolk mixture until just combined.
Cook and serve
Heat an omelet pan and rub the edges with butter.
Pour the omelet mixture into the hot pan and spread it evenly.
Cook until slightly browned underneath, lifting the pan to prevent burning.
Transfer to the oven to dry the top without browning.
Once the center is dry, run a knife around the edge and fold the omelet in half.
Invert the omelet onto a hot platter.

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 set and give the omelet its light, airy structure.
- Egg yolks
- Yolks add richness and flavor and set to form a tender, custardy body.
- Milk
- Adds moisture that turns to steam, keeping the omelet soft and tender.
- Butter
- Greases the pan so the omelet releases cleanly and adds a rich flavor.
The step that matters
Folding the whites into the yolk mixture. Folding gently keeps the air beaten into the whites. Stirring or overmixing deflates them, leaving a dense, flat omelet instead of a light one.
