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 Puffs
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 mixture
Combine sugar and lemon juice in a bowl and beat together.
Whisk egg white until very frothy, then add to mixture and whisk for 20 minutes.
Add grated lemon rind and 3 eggs, mixing well.
Bake
Sift sugar over wafer paper, drop small quantities of mixture onto it, and bake in a moderate oven at 350°F (175°C).

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
- Bind the mixture and give the puffs structure as they set in the oven.
- Egg white
- Whisked until frothy, it traps air that lightens the mixture and helps the puffs rise.
- Loaf sugar
- Sweetens the puffs and helps form a crisp, lightly browned surface when baked.
- Lemon juice
- Adds acidity and bright lemon flavour that balances the sweetness.
- Lemon rind
- Adds aromatic lemon oil for fragrance without adding much liquid.
The step that matters
Whisking the egg white and sugar mixture. Egg white must be whisked until very frothy so it traps air. Under-whisking gives dense puffs that do not rise, while the air bubbles expand in the oven to lighten the texture.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
