Boston Brown Bread

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the batter

  1. Measure and sift the rye meal, corn meal, graham flour, salt, and baking soda into a bowl.

  2. Add the molasses and sour milk, then beat well until combined.

  3. Pour the mixture into a buttered mold.

Steam and finish

  1. Steam for 3½ hours, ensuring the water in the kettle is boiling and comes halfway up the side of the mold.

  2. Add boiling water as needed to maintain the level.

  3. After steaming, remove the cover and place the mold in a 400°F (200°C) oven for 10 minutes.

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

What each ingredient does

Rye meal
Adds earthy flavour and a dense, hearty crumb.
Corn meal
Gives the bread its coarse texture and body.
Graham flour
Adds structure and a nutty, wholesome flavour.
Baking soda
Reacts with the sour milk to lift and lighten the batter.
Molasses
Adds sweetness, moisture and a deep brown colour.
Sour milk
Provides acidity to activate the baking soda and keeps the crumb moist.

The step that matters

Keeping the steaming water boiling and at the right level. If the water stops boiling or drops below the mold's halfway point, steam weakens and the bread cooks unevenly and turns heavy. Adding boiling water keeps the heat and steam steady throughout the long steam.
