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

What each ingredient does

Gelatine
Sets the mixture so the sponge holds its shape when chilled.
Egg whites
Whipped to stiff peaks, they trap air to give the sponge its light, airy texture.
Apples
Provide the fruit base and moisture that the sponge is built on.
Loaf sugar
Sweetens the dish and helps dissolve into a syrup with the water.

The step that matters

Fold the apple mixture into the whipped egg whites. Folding gently keeps the air bubbles in the whipped whites intact. Stirring vigorously would deflate the foam and leave the sponge dense rather than light.

Swap the apple

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

  1. Orangefits better
  2. Vanillafits better
  3. Limefits better
  4. Applethe original

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