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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Beat the egg yolks and powdered sugar together until light and creamy.
Add a few drops of lemon or vanilla extract.
In a separate bowl, beat the egg whites until stiff peaks form.
Gently fold the beaten egg whites into the yolk mixture using a rotary motion.
Bake and serve
Pour the mixture into a buttered baking dish that is 2 to 3 inches deep.
Smooth the top and sprinkle with additional sugar.
Bake in a moderate oven at 350°F (175°C) until it has risen and is a fine yellow color.
Serve immediately, as it will fall if left to sit.

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 that makes the soufflé rise and turn light.
- Egg yolks
- Combined with sugar to form a rich, creamy base that gives the dish its flavor and color.
- Powdered sugar
- Sweetens the base and helps the yolks become light and creamy when beaten.
The step that matters
Fold the beaten egg whites gently. Folding gently keeps the air bubbles in the whipped whites intact. Those bubbles expand in the oven and lift the soufflé. Vigorous stirring deflates the foam, so it rises less and may turn dense.
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.
