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

What each ingredient does

Egg whites
Whipped into stiff peaks, they trap air and give the soufflé its light, airy structure.
Gelatine
Sets the liquid mixture so it holds its molded shape when chilled.
Sugar
Adds sweetness and softens the sharpness of the lemon.
Lemon juice
Adds acidity that brightens the flavour and balances the sugar.

The step that matters

Stir the beaten whites into the cooled mixture. If the gelatine mixture is still hot, it will deflate the whipped egg whites and the air will escape. If it has already set, it will leave lumps. Letting it cool to a thick, syrupy state keeps the foam light and evenly blended.

Swap the lemon

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

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

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