Why it works: Lemon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Sweet Omelet
Ingredients
Directions
Prepare the eggs
Separate the eggs, ensuring no yolk gets into the whites.
Beat the yolks until thick and creamy, then add granulated sugar, salt, and lemon extract.
Beat the egg whites until stiff, then fold in the powdered sugar.
Combine and cook
Gently pour the yolk mixture over the whites and fold in lightly with a knife.
Heat butter in a frying pan until melted, then add the omelet mixture by the teaspoonful.
Cook until browned on the underside, then place in the oven to set for a few moments.
Serve
Fold the omelet over and turn it out onto a hot dish, dust with powdered sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air when beaten, giving the omelet its light, airy structure, while yolks add richness and body.
- Granulated sugar
- Adds sweetness to the yolk mixture and helps it turn thick and creamy when beaten.
- Powdered sugar
- Sweetens the whites and gives a dusted, sweet finish on the outside of the omelet.
- Butter
- Provides fat for frying, helping the underside brown and adding rich flavor.
The step that matters
Folding the yolk mixture into the whites. Whites beaten to stiff peaks hold the air that lifts the omelet. Folding gently keeps that air in, while stirring or overmixing deflates the foam and leaves a dense, flat result.

Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
