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 ↓
Lemon Souffle
Ingredients
Directions
The book says “a slow oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the base
Preheat the oven to 400°F (200°C).
Beat the egg yolks until thick and lemon colored.
Gradually add the sugar while continuing to beat.
Mix in the lemon rind and juice.
Fold and bake
In a separate bowl, beat the egg whites until stiff.
Gently cut and fold the beaten egg whites into the yolk mixture.
Pour the mixture into a buttered pudding dish.
Set the dish in a pan of hot water and bake for 35 to 40 minutes.
Serve with or without sauce.

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 yolks
- Provide richness and structure through emulsifying fat and thickening when beaten and baked.
- Egg whites
- Whipped to stiff foam, they trap air that lifts the souffle as it bakes.
- Sugar
- Sweetens the dish and helps stabilize the beaten yolks and whites.
- Lemon juice
- Adds acidity that brightens the flavor and balances the sweetness.
- Lemon rind
- Contributes concentrated lemon aroma from the aromatic oils in the peel.
The step that matters
Folding in the beaten egg whites. Cutting and folding gently keeps the air bubbles in the whipped whites. Stirring hard deflates the foam, so the souffle bakes 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.
