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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the mixture
Sift the sugar into a bowl.
Grate the lemon rind and mix it with the sugar.
Beat the egg whites until stiff, then add them to the sugar and lemon mixture.
Beat the mixture for 1 hour until well combined.
Shape and bake
Shape the mixture as desired and place it on parchment paper on baking sheets.
Bake in a moderate oven at 350°F (175°C).
Cool and release
Do not remove the paper until the puffs are cold.
Oil the paper to help it come off easily.

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
- Double-refined sugar
- Sweetens the puffs and helps stabilise the whipped egg white foam.
- Egg whites
- Whipped to a foam, they give the puffs their light, airy structure as they set.
- Lemon rind
- Adds citrus aroma and flavour without adding liquid.
The step that matters
Leave the puffs on the paper until cold. Puffs are soft and fragile while warm and only firm up as they cool. Lifting them too early can tear or flatten them, so they should stay on the paper until fully cold.
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.
