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

What each ingredient does

Egg yolks
Add richness and structure to the batter as they are beaten light.
Egg whites
Whipped and folded in to lighten the batter and help it rise.
Granulated sugar
Sweetens the cake and helps the batter hold air when beaten.
Flour
Provides the main structure that sets as the cake bakes.
Baking powder
Releases gas in the batter to make the cake rise.

The step that matters

Fold in the well-beaten egg whites. Folding gently keeps the air whipped into the egg whites. Stirring or deflating them makes the cake dense instead of light.

Swap the vanilla

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

  1. Raisinfits better
  2. Vanillathe original
  3. Lemonfits less well
  4. Figfits less well

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