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 meringue
Boil the sugar until it reaches the boil degree, then place the sugar boiler in a bowl of cold water.
Whip the egg whites until stiff and frothy.
Gradually mix the boiled sugar with the whipped egg whites using the back of a spoon, ensuring even consistency.
Add the lemon juice and liqueur, mixing thoroughly but gently.
Shape and dry
Shape the meringue into small forms using a biscuit forcer.
To color, add a few drops of cochineal for pink, saffron for yellow, or chocolate for brown.
Dry the meringues in the oven at a low temperature, ensuring it does not color a piece of white paper.

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 a syrup, it sets the structure of the meringue and sweetens it.
- Egg whites
- Whipped into a foam that gives the meringue its airy structure.
- Lemon juice
- Adds acidity, which helps stabilize the whipped egg white foam.
The step that matters
Gradually mix the boiled sugar with the whipped egg whites. Adding hot syrup too quickly or unevenly can deflate the foam or leave it lumpy. Pouring it in a steady stream while mixing keeps the foam stable and the texture even.
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.
