Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the mixture and give it a rich, creamy set when heated.
Sugar
Sweetens the cream and balances the sharpness of the lemon juice.
Lemons
Provide the juice and aromatic peel that flavour the cream.

The step that matters

Heat until thick and scalding hot, stirring constantly. Egg yolks thicken as their proteins set with heat, but overheating or uneven heat can curdle them into lumps. Steady stirring over the fire spreads the heat evenly so the cream thickens smoothly.

Swap the lemon

How well each one fits the dish's main ingredients (sugar, egg):

  1. Vanillafits better
  2. Raisinfits about as well
  3. Lemonthe original
  4. 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.
