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

What each ingredient does

Cornstarch
Thickens the lemon liquid into a soft, sliceable float once boiled.
Egg whites
Form a light, airy topping that sits over the orange layer.
Sugar
Sweetens the lemon liquid and balances its acidity.
Lemons
Provide tart, aromatic juice that flavours the thickened liquid.

The step that matters

Boil while stirring. Cornstarch must be stirred as it boils so it gelatinises evenly; otherwise it can clump or scorch on the bottom, leaving lumps and an uneven, thickened texture.

Swap the lemon

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

  1. Strawberryfits better
  2. Figfits better
  3. Raspberryfits better
  4. Lemonthe original

Fit is the average pairing score against sugar, orange, egg, vanilla, cream. Candidates are from the same food group and used in at least 100 recipes.
