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

What each ingredient does

Gelatine
Sets the liquid into a light, wobbly structure as it cools.
Egg whites
Whipped to stiff foam, they give the dessert its airy, snowy texture.
Sugar
Sweetens the dessert and balances the sharpness of the lemon juice.
Lemon juice
Adds acidity that brightens the flavour and cuts the sweetness.
Egg yolks
Used for decoration around the dish, not as a structural part of the set.

The step that matters

Pouring the beaten egg whites onto the mixture. Egg whites must be beaten until stiff, and the mixture should be nearly cold before they are added. If the gelatine is still warm, the foam can deflate or sink instead of staying light on top as the base sets.

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.
