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 ↓
Italian Meringues
Ingredients
Directions
Make the syrup
Boil the sugar until it reaches the soft ball stage.
Set the sugar boiler in a bowl of cold water.
Make the meringue
Whip the egg whites until stiff and frothy.
Gradually mix the sugar into the whipped egg whites using a spoon.
Add the lemon juice and liqueur, mixing thoroughly but lightly.
Shape
Shape the meringue paste into small forms using a biscuit forcer.
Optionally, color the meringue with a few drops of cochineal.

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
- Boiled to soft ball stage, it forms a syrup that sets the whipped whites into a stable meringue.
- Egg whites
- Whipped into a foam that traps air and gives the meringue its structure.
- Lemon juice
- Adds acidity that helps stabilize the whipped egg white foam.
- Liqueur
- Adds aroma and flavour to the meringue.
The step that matters
Gradually mix the sugar into the whipped egg whites. Pouring the hot syrup in slowly, while whisking, cooks the whites gently and keeps the foam glossy and stable. Adding it too quickly can deflate the foam and make the meringue weep or lose volume.
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.
