Barley and Oat Bread

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat your oven to 350°F (175°C).

  2. In a large bowl, combine the barley flour, ground rolled oats, baking powder, and salt. Mix well until all dry ingredients are evenly distributed.

  3. Pour the mixture into a greased loaf pan.

Bake

  1. Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean.

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

What each ingredient does

Barley flour
Provides the main body of the bread, though it has less gluten to hold it together.
Ground rolled oats
Adds bulk and a soft, tender crumb with moisture-holding starch.
Baking powder
Releases gas as it heats, lifting the batter so the loaf rises in the oven.

The step that matters

Mixing the dry ingredients evenly. Baking powder must be spread through the flour and oats so every part of the loaf rises evenly; clumps can leave bitter pockets or dense spots.
