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 ↓
Omelet Souffle
Ingredients
Directions
Prepare
Separate the egg whites from the yolks.
Mix the yolks with the powdered sugar and chopped lemon rind.
Whip the egg whites until stiff and fold them into the yolk mixture.
Cook
Melt the butter in a frying pan over medium heat.
Pour the egg mixture into the pan and stir to combine with the butter.
Strain the mixture into a buttered dish and place it on hot ashes.
Finish
Sprinkle powdered sugar on top and carefully brown the surface with a salamander.

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 lift, while yolks add richness and a custard-like set.
- Butter
- Adds fat and richness, and helps keep the mixture from sticking to the pan.
- Powdered sugar
- Sweetens the dish and browns on the surface under direct heat.
- Lemon rind
- Adds bright citrus aroma and flavour to the yolk mixture.
The step that matters
Folding the whipped whites into the yolks. Whites hold air only while whipped, so folding gently rather than stirring keeps the mixture light. Overmixing deflates the foam, and the dish loses its rise and soufflé texture.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
