Oat Flake Bread

Oven, in the book's wordsA very slow oven

Ingredients

Directions

The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the batter

  1. Mix the baking soda with the buttermilk and molasses separately.

  2. Combine the buttermilk and molasses in a large bowl.

  3. Stir in the oat flakes, then add the flour and salt.

  4. Flour the raisins with a little extra flour and fold them into the mixture.

Bake

  1. Grease five 1-pound baking powder cans and fill them a little over half full with the batter.

  2. Cover the cans and bake for 1½ hours.

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

What each ingredient does

Baking soda
Reacts with the acidic buttermilk to produce gas that lifts the bread.
Buttermilk
Its acidity activates the baking soda and adds moisture and tenderness.
Molasses
Adds sweetness, dark color, and moisture to the crumb.
Oat flakes
Provide the bulk and hearty, chewy texture of the loaf.
Flour
Adds structure that helps the batter hold its shape while baking.

The step that matters

Fill the cans only a little over half full. The batter rises during baking as the baking soda reacts with the acidic buttermilk. Filling past half leaves too little room, so the batter can overflow or bake unevenly.
