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

What each ingredient does

All-purpose flour
Provides the structure that holds the cake's airy crumb once baked.
Granulated sugar
Sweetens the cake and helps keep the crumb soft and tender.
Baking powder
Releases gas during baking so the batter rises and becomes light.
Boiling water
Adds moisture and helps the starch swell, keeping the cake tender.
Egg whites
Trapped air from beating them lifts the batter and sets the cake's structure.

The step that matters

Gently fold in the beaten egg whites. The air whipped into the egg whites is what makes the cake rise. Stirring or deflating them vigorously knocks out that air, leaving a dense, flat sponge.

Swap the vanilla

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

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

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
