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

What each ingredient does

Flour: Provides the structure that holds the loaf together as it bakes.
Eggs: Bind the batter and add structure and richness to the crumb.
Butter: Adds fat for tenderness and flavor in the crumb.
Brown sugar: Adds sweetness and moisture, and helps the loaf brown and stay soft.
Buttermilk: Adds moisture and acidity that works with the leavening to lift the crumb.
Baking soda: Reacts with the acidic buttermilk to produce gas that helps the loaf rise.

The step that matters

Stir in buttermilk alternately with flour mixture. Adding the flour and buttermilk in alternating additions keeps the batter smooth and balanced. Overmixing after the flour goes in develops gluten, which can make the loaf tough.
