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 quick oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Prepare the mixture
Beat and sift the sugar.
Grate the lemon rind and mix it with the sugar.
Beat the egg whites until stiff, then add them to the sugar and lemon rind.
Beat the mixture for 1 hour.
Shape and bake
Shape the mixture as desired and place it on paper-lined tin plates.
Bake in a moderate oven (350°F / 175°C) until set, about 15-20 minutes.
Do not remove the paper until the puffs are cold.

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
- Sugar
- Provides sweetness and the bulk of the structure of the puffs.
- Egg whites
- Whipped to stiff foam, they trap air and give the puffs their light, set structure.
- Lemon rind
- Adds aromatic lemon oils for flavour without adding liquid.
The step that matters
Beat the mixture for 1 hour. Long beating keeps air trapped in the whipped egg whites and dissolves the sugar into them, which gives the puffs their light texture once baked.
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.
