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 batter
Mix the sugar with the juice of the lemons.
Beat the egg whites until frothy and add to the lemon and sugar mixture.
Beat the mixture for 30 minutes.
Beat the 3 whole eggs and add them along with the grated lemon rind to the mixture.
Mix everything well.
Bake
Sprinkle finely powdered sugar on a baking sheet and drop spoonfuls of the mixture onto it.
Bake in a moderate oven at 350°F (175°C) for a few minutes.

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
- Powdered sugar
- Sweetens the batter and dissolves into the lemon juice to form a light, sweet base.
- Egg whites
- Beaten to a froth, they trap air that lifts the puffs as they bake.
- Whole eggs
- Add richness and structure, helping the puffs hold their shape after baking.
- Lemon juice
- Adds sharp acidity and bright lemon flavour that balances the sugar.
- Lemon rind
- Carries aromatic lemon oils, adding fragrance and flavour to the batter.
The step that matters
Beating the mixture for 30 minutes. Long beating incorporates and holds air in the egg foam, which gives the puffs their lift. Under-beating leaves them dense and flat, while the batter must still be spooned out before the foam collapses.
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.
