Why it works: Lemon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Lemon Puffs
Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Beat the yolks and sugar until very stiff.
Add the beaten egg whites and mix well.
Flavor with lemon juice and lemon peel extract or citric acid.
Bake and cool
Drop small cakes onto buttered paper.
Bake at 400°F (200°C) without browning.
Leave the puffs on the paper until completely cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and structure to the batter, helping it hold its shape.
- Egg whites
- Whipped to trap air, giving the puffs their light, airy lift.
- Pulverized loaf sugar
- Sweetens the puffs and helps stiffen the yolk mixture as it is beaten.
- Lemon juice
- Adds acidity that brightens the flavor of the puffs.
The step that matters
Bake without browning. Baking at 400°F sets the structure of the whipped egg foam, but overbaking dries the puffs and promotes browning, which makes them tough and bitter. Watch them closely.
Swap the lemon
How well each one fits the dish's main ingredients (sugar, egg, butter):
- Vanillafits better
- Lemonthe original
- Raisinfits about as well
- Figfits about as well
Fit is the average pairing score against sugar, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
