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 ↓
To Make Omelets
Ingredients
Directions
Prepare
Beat the egg yolks lightly, about 12 times, avoiding overbeating.
Add milk, salt, pepper, and flour if using; mix well.
Beat the egg whites in a separate bowl until stiff peaks form.
Cook
Heat a skillet until very hot but not smoking, then add butter and let it melt.
Pour the egg mixture into the skillet; it should bubble and rise.
Use a thin knife to lift the edges occasionally to prevent burning.
Once the bottom is set, fold the omelet in half, slide it onto a hot platter, and serve immediately.

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
- Proteins set into the structure of the omelet; whipped whites add lightness and help it rise.
- Milk
- Adds moisture and water that turns to steam, keeping the omelet tender.
- Butter
- Adds fat and flavor and helps the surface brown lightly in the pan.
The step that matters
Heating the skillet. The butter should melt and foam without burning, and the eggs should bubble and rise. If the pan smokes, the butter scorches and the bottom browns before the eggs set evenly, giving a bitter taste.
