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
Make the lemon base
Grate the rind of the lemons and juice them.
In a saucepan over boiling water, combine the lemon juice, grated rind, and sugar.
Beat the yolks of the eggs and add them to the mixture.
Thicken and finish
Beat the egg whites until stiff peaks form.
Stir the mixture over boiling water until it thickens like custard.
Pour the hot mixture over the beaten egg whites and mix well.
Chill in the refrigerator and serve in glasses.

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
- Eggs
- Yolks thicken the mixture like custard, while whites whip into a light, airy structure.
- Sugar
- Sweetens the cream and helps balance the sharpness of the lemon.
- Lemons
- Juice and rind supply acidity and aroma that flavour the cream.
The step that matters
Thickening the custard over boiling water. Egg yolks thicken as they heat, but if the mixture gets too hot it can curdle or turn grainy. Stirring gently over simmering water keeps the heat even so the cream sets smooth.
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.
