Why it works: Lemon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Lemon 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
Preheat the oven to 400°F (200°C).
In a bowl, beat the egg yolks and gradually add the sugar while continuing to beat.
Add the grated lemon rind and juice to the mixture.
In a separate bowl, beat the egg whites until very light and fluffy.
Fold the beaten egg whites into the yolk mixture gently.
Grease a pudding dish with butter and pour the batter into it.
Bake and serve
Place the pudding dish in a pan of hot water and bake for 30 to 45 minutes.
Serve warm, with or without sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into foam, they trap air that lifts the soufflé as it bakes.
- Egg yolks
- Enrich the batter and add richness and structure as they set.
- Sugar
- Sweetens the batter and helps stabilise the beaten yolks.
- Lemon rind and juice
- Add aroma and acidity that brightens the sweetness of the batter.
The step that matters
Folding the beaten egg whites into the yolk mixture. Folding gently keeps the air bubbles in the whites intact. Overmixing deflates the foam, so the soufflé rises less and turns dense.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, butter):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
