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

What each ingredient does

Eggs
Yolks enrich the batter and whites, beaten stiff and folded in, lighten the crumb.
All-purpose flour
Gluten forms the structure that holds the cake's crumb together as it bakes.
Butter
Creamed with sugar, it traps air and adds tenderness and richness to the crumb.
Sugar
Creamed with butter, it adds sweetness and helps the cake brown.
Baking powder
Releases gas in the batter, causing the cake to rise.
Mashed bananas
Add moisture, sweetness and banana flavor to the crumb.

The step that matters

Folding in the egg whites. Stiffly beaten whites hold air that gives the cake its lift. Overmixing or stirring vigorously deflates them, leaving a dense cake, so fold gently until just combined.

Swap the banana

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

  1. Figfits better
  2. Raisinfits about as well
  3. Coconutfits about as well
  4. Bananathe original

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