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
Pass the sugar through a fine sieve, place it in a bowl with the lemon juice, and beat well together.
Beat the egg white to a high froth and add it to the bowl.
Beat for another 30 minutes.
Add the whole eggs and grated lemon rinds to the mixture and mix well.
Bake
Dust kitchen paper with sugar.
Drop small amounts of the mixture onto it.
Bake in a moderate oven at 350°F (175°C) until puffs are set.

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
- Adds sweetness and helps stabilise the beaten mixture.
- Egg white
- Beaten to a high froth, it traps air that lifts the puffs.
- Whole eggs
- Add structure and richness so the puffs hold their shape when set.
- Lemon juice
- Adds bright acidity and citrus flavour.
- Lemon rind
- Adds concentrated lemon aroma from the oils in the peel.
The step that matters
Beating the egg white to a high froth. The air whipped into the egg white is what makes the puffs rise and turn light. If the foam is underbeaten, the mixture stays dense and the puffs bake up flat and heavy.
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.
