Ingredients

Directions

Prepare

Preheat oven to 325°F (165°C / gasmark 3).
Use cooking spray or grease and then lightly flour a 9x5x3‑inch baking pan.

Make the dough

Combine flour, baking soda, and salt in a large mixing bowl.
Form a cavity in the middle and pour in the buttermilk.
Mix until just moistened. Too much mixing will make it tough.
Gently shape the dough to fit pan.

Bake and rest

Cut the top at least three times with a knife.
Bake for 65–70 minutes, or until a toothpick inserted in the bread comes out clean.
Cool on a wire rack.
Wrap in tea‑towel or foil several hours or overnight for best flavor.

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

What each ingredient does

Whole-wheat flour: Adds a nutty flavor and a denser, heartier crumb to the loaf.
Flour: Provides the structure that holds the loaf together as it bakes.
Baking soda: Reacts with the acid in buttermilk to produce gas that lifts the bread.
Buttermilk: Its acidity activates the baking soda and its moisture hydrates the flour.

The step that matters

Mix until just moistened. Overmixing develops gluten in the flour, making the bread tough and dense. Stopping once the dry ingredients are just wet keeps the crumb tender.
