Boston Brown 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.

Prepare

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

  2. In a large bowl, mix the graham flour, white flour, corn meal, and salt.

  3. In another bowl, combine the molasses, baking soda, cold water, melted lard, and sour milk.

Mix and bake

  1. Pour the wet ingredients into the dry ingredients and mix until well combined.

  2. Pour the batter into a greased loaf pan.

  3. Bake for about 1 hour 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

Graham flour
Provides the hearty, coarse structure and nutty flavor that defines the bread.
Corn meal
Adds a gritty texture and helps give the loaf its dense, crumbly body.
Molasses
Adds sweetness, dark color, and moisture while deepening the flavor.
Baking soda
Reacts with the sour milk's acid to produce gas that lifts the batter.
Sour milk
Its acidity activates the baking soda and tenderizes the crumb.
Melted lard
Adds fat that keeps the crumb moist and tender.

The step that matters

Combining the wet and dry ingredients. Mix only until just combined. Once the baking soda meets the acidic sour milk, it starts releasing gas, so a gentle stir keeps the air bubbles and lift intact, while overmixing can make the loaf dense and tough.
