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 Souffle
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the omelette
Beat the yolks of 8 eggs with 1 tablespoon of water, ¼ teaspoon salt, 1 tablespoon sugar, and the juice of 1 lemon.
Fry the egg mixture in a pan until cooked.
Transfer the cooked mixture to a serving dish.
Top and bake
Whip the 4 reserved egg whites to a froth with additional sugar.
Spread the whipped egg whites over the cooked eggs.
Bake at 350°F (175°C) for a few minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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
- Eggs
- Set the cooked base and provide the structure of the omelette.
- Egg whites
- Whipped into a foam that traps air, giving the topping its light, risen texture.
- Sugar
- Adds sweetness and helps stabilize the whipped egg white foam.
- Lemon juice
- Adds acidity that helps stabilize the whipped egg white foam.
The step that matters
Whipping the egg whites. Egg whites beaten to a stiff froth trap air, which lets the topping rise in the oven. Under-whipped whites are runny and deflate, while over-whipped whites turn dry and grainy.
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.
