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 ↓
Omelette Souffle
Ingredients
Directions
Prepare
Separate the whites from the yolks of the eggs, removing any specks.
Add the sugar and lemon juice to the yolks and mix well.
Whip the egg whites until firm, then gently fold them into the yolk mixture.
Cook
Melt a small piece of butter in a frying pan over low heat.
Pour the omelette mixture into the pan, being careful not to burn it.
Finish and serve
Turn the omelette out onto a dish and sprinkle sugar over it to glaze.
Place the dish in the oven until it rises, glaze it again, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites trap air for a light, risen structure, while yolks add richness.
- Sugar
- Sweetens the omelette and forms a glaze on the surface.
- Lemon juice
- Acidity helps stabilise the whipped egg whites.
- Butter
- Fat for frying that adds flavour and helps prevent sticking.
The step that matters
Fold the whipped whites gently into the yolk mixture. Folding gently keeps the air bubbles in the whipped whites. Stirring or beating them down deflates the foam, which leaves the omelette dense rather than soufflé-like.
Swap the lemon

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