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

What each ingredient does

Eggs: Bind the batter and add structure as they set during baking.
Bananas: Add moisture and natural sweetness to the crumb.
All-purpose flour: Forms the main structure of the loaf as its proteins set in the oven.
Baking powder: Releases gas during baking so the loaf rises and becomes light.
Shortening: Adds fat that tenderizes the crumb and carries the butter flavor.
Brown sugar: Adds moisture, softness, and caramel-like flavor to the crumb.

The step that matters

Cream sugars and shortening. Beating sugar into fat traps air bubbles that help the loaf rise and give it an even, tender texture. Under-creaming leaves a denser bread.
