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 ↓
Vert Good Lemon Creams
Ingredients
Directions
Prepare
Thinly slice the rinds of the lemons and combine them with sugar and spring water in a bowl. Let sit for 6 hours.
Strain the mixture and add the juice of the lemons and the beaten eggs. Strain again to remove any solids.
Cook
Remove the lemon rinds and stir the mixture continuously over gentle heat for 6 to 8 minutes until it thickens slightly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Their proteins set when gently heated, thickening the mixture into a cream.
- Sugar
- Sweetens the cream and balances the sharp acidity of the lemons.
- Lemons
- Provide acidity and fragrant oils from the rinds and bright flavour from the juice.
The step that matters
Heat gently and stir continuously. Egg proteins set at moderate temperatures and thicken the cream smoothly. Overheating or pausing to stir can curdle or scramble the eggs into lumps.
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.
