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 ↓
Omelette Soufflée
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 the batter
In a bowl, mix and beat the egg yolks with the powdered sugar and grated lemon peel until well combined.
In a separate bowl, whip the egg whites until very stiff peaks form.
Gently fold the whipped egg whites into the yolk mixture until just combined.
Bake and serve
Pour the mixture into a greased baking dish and bake in a preheated oven at 400°F (200°C) until puffed and golden.
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 into stiff peaks, they trap air and give the soufflé its light, risen structure.
- Egg yolks
- Add richness and body to the batter and help set the structure as it bakes.
- Powdered sugar
- Sweetens the batter and dissolves easily into the yolks for a smooth base.
The step that matters
Folding the whipped egg whites into the yolk mixture. Folding gently keeps the air bubbles in the whites intact. Stirring or beating vigorously deflates the foam, so the soufflé will bake flat and dense instead of rising.
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.
“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.
