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

What each ingredient does

Flour: Forms the structure that holds the cake's crumb together.
Eggs: Bind the batter and add structure and richness as they set in the oven.
Sugar: Sweetens the cake, promotes browning, and helps trap air when creamed with butter.
Bananas: Add moisture and natural sweetness to the crumb.
Sour cream: Adds moisture, fat and tang, and tenderizes the crumb.
Baking soda: Reacts with acidic ingredients to produce gas that lifts the cake.

The step that matters

Alternating the dry and wet additions. Adding the flour mixture and sour cream in alternating portions, beginning and ending with dry, keeps the batter smooth and emulsified. Mixing gently after the flour goes in limits gluten development, which keeps the cake tender rather than tough.

Swap the pecans
