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

What each ingredient does

Butter
Creams with sugar to trap air and give the loaf a tender, rich crumb.
Egg
Binds the batter and adds structure and richness as it is beaten light.
Baking powder
Releases gas in the batter, helping the loaf rise in the oven.
Baking soda
Reacts with the acidic sour milk to produce gas and lift the batter.
Sour milk
Its acidity activates the baking soda and adds moisture and tenderness.
Bran
Adds fiber-rich body and a coarse, hearty texture to the crumb.

The step that matters

Adding the flour mixture alternately with the sour milk. Overmixing once flour meets liquid develops gluten, making the bread tough and dense. Mix just until combined, then add the prunes gently so the batter stays light and even.
