Graham 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.

Mix all the ingredients together until well combined.
Pour the mixture into a loaf pan.
Bake in a preheated oven at 350°F (175°C) until golden brown and a toothpick comes out clean.

What each ingredient does

Graham flour: Provides the bulk and the coarse, hearty texture of the loaf.
White flour: Adds gluten-forming structure so the loaf holds its shape better than bran alone.
Sour milk: Its acidity reacts with the baking soda to produce gas that helps the loaf rise.
Baking soda: Reacts with the acid in the sour milk to release carbon dioxide for lift.
Baking powder: Supplies additional leavening so the batter rises during baking.
Sugar: Adds sweetness and helps the crust brown.
