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

What each ingredient does

All purpose flour
Forms the structure that holds the loaf together as it sets in the oven.
Eggs
Bind the batter and help it set, adding structure and richness to the crumb.
Mashed bananas
Add moisture and natural sweetness, helping the loaf stay tender.
Sour cream
Adds moisture and a tender texture, with a slight tang that balances sweetness.
Baking soda
Reacts with the acidic ingredients to produce gas that lifts and aerates the loaf.
Vegetable oil
Provides fat that keeps the crumb moist and tender after baking.

The step that matters

Stir just until dry ingredients are moistened. Once flour is mixed with liquid, gluten begins to develop. Overmixing makes the bread tough and dense, so stop as soon as no dry streaks remain.
