Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Omelet Souffle
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Grease a small baking dish.
Beat the egg whites until very stiff.
Beat the egg yolks until creamy.
Fold the yolks into the egg whites.
Add the powdered sugar and lemon juice, and stir quickly.
Pour the mixture into the baking dish.
Bake and serve
Sprinkle with additional powdered sugar.
Bake at 400°F (200°C) until light brown.
Serve immediately.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 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
- Egg whites
- Whipped to stiff foam, they give the omelet its light, airy structure.
- Egg yolks
- Beaten until creamy, they add richness and flavor to the airy base.
- Powdered sugar
- Adds sweetness and helps the omelet brown lightly in the oven.
- Lemon juice
- Adds acidity that brightens the flavor of the eggs and sugar.
The step that matters
Fold the yolks into the egg whites. Egg whites hold air only when stiff and unbroken. Folding gently keeps the foam intact, so the omelet rises and stays light instead of deflating.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
