Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lemons
- Provide the aroma and sharp acidity that flavour the cream.
- Sugar
- Sweetens the cream and balances the lemon's acidity.
- Eggs
- Thicken the mixture as gentle heat sets their proteins.
- Spring water
- Dissolves the sugar and draws flavour from the lemon rinds.
The step that matters
Stir the mixture continuously over gentle heat for 6 to 8 minutes until it boils softly.. Eggs set through gentle heat, and stirring spreads the heat evenly. Too much heat or unstirred spots can scramble the eggs and leave the cream grainy.
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.
