Why it works: Butter and egg 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
Prepare
Put a tablespoonful of butter in a smooth skillet.
While the butter melts, break five eggs.
Beat the eggs only enough to break the yolks (about twenty strokes), then add salt and pepper.
Cook the omelet
As soon as the butter bubbles, pour the eggs into the skillet.
Hold the skillet with one hand and gently shake it all the time.
With a spoon in the other hand, draw the eggs from the edges of the pan to the center.
As soon as the eggs become a little firm but not hard, fold one half over the other.
Serve
If you are an expert, toss the omelet by shaking the skillet to the exact center of a platter; otherwise lift it out with a cake turner.
Serve immediately.

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.

Shared aroma: 2-nonenal (fatty, green).
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 a delicate structure when heated, forming the body of the omelet.
- Butter
- Coats the skillet so the eggs release cleanly and add richness.
The step that matters
Fold the omelet while the eggs are still a little moist. Eggs keep cooking from residual heat after they leave the pan. Folding once they are just firm but not hard keeps the interior tender instead of rubbery and dry.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
