Why it works: Lemon and sugar 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 ↓
Cold Lemon Pudding
Ingredients
Directions
Make the base
Mix the cornflour with a little cold water.
Pour boiling water over the mixture until it is clear, like making starch.
Add the lemon juice, grated rind, sugar, and egg yolks.
Pour into a crystal dish.
Finish and serve
Once cold, top with the beaten egg whites mixed with a little sugar.
Decorate with cherries or a little red jelly.

Lemon and sugar 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
- Cornflour
- Thickens the liquid into a clear, set custard as it cooks with the boiling water.
- Eggs
- Egg yolks enrich and thicken the pudding; beaten whites add a light, airy topping.
- Lemon
- Juice and rind supply sharp acidity and fragrant citrus aroma that balance the sweetness.
- Sugar
- Sweetens the pudding and the meringue-style topping.
The step that matters
Pour boiling water over the cornflour until it is clear. Cornflour only thickens fully when it is heated with enough hot liquid for its starch granules to swell and gelatinise. Stopping early leaves the mixture cloudy and runny, so it will not set properly.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits about as well
- Lemonthe original
- Datesfits less well
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
