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

What each ingredient does

Powdered sugar
Sweetens the cream and adds bulk to its body.
Lemon juice and rind
Provides acidity and bright lemon aroma that flavour the cream.
Egg whites
Whipped to foam, they give the cream its light structure and body when cooked.

The step that matters

Cook the mixture briefly to thicken. Heating egg-white mixtures gently thickens them, but overheating can curdle or toughen the eggs. Cook just until thick, watching closely.

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.
