Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Plain Omelet
Ingredients
Directions
Beat the eggs slightly and add the water, salt, and pepper.
Melt the butter in a frying pan over low heat.
Pour in the egg mixture.
As it thickens, lift the edges to allow the uncooked part to run underneath.
When the top is creamy and the bottom is brown, the omelet is done.
Serve immediately on a hot platter.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Egg and pepper barely smell alike, yet cooks put them together in 50,580 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
- Set into the structure of the omelet as they cook, forming its body.
- Butter
- Adds richness and helps keep the eggs from sticking while the bottom browns.
The step that matters
Lifting the edges as the egg thickens. Egg proteins set as they heat. Lifting the edges lets the still-liquid egg flow underneath to cook, which keeps the omelet tender instead of rubbery or overcooked in spots.
