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 ↓

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.
Prepare the meringue
Beat the egg whites for 2 hours in a cool place until stiff.
Flavor the mixture with lemon or rose water.
Drop a few drops of water on a sheet of paper on a shallow tin.
Bake
Drop spoonfuls of the mixture onto the wet spots.
Bake in a moderate oven at 350°F (175°C) for about 15 minutes until pale brown or cream color.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into a stiff foam that gives the cakes their light, airy structure.
- Loaf sugar
- Sweetens the cakes and helps stabilize the whipped egg white foam.
The step that matters
Beat the egg whites until stiff. Egg whites must be whipped until they hold firm peaks, since the foam supplies all the lift. Underbeaten whites collapse and spread, and any trace of fat or yolk prevents the foam from forming properly.
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.
