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 the batter

  1. Mix the rye flour and cornmeal together in a bowl.

  2. Dissolve the baking soda in boiling water and add it to the sour milk along with the molasses.

  3. Combine the wet mixture with the dry ingredients and add the salt; stir well.

  4. Pour the batter into a well-greased 2‑quart bread mold.

Steam and bake

  1. Cover the mold and steam for 5 hours.

  2. Remove the lid and bake in a preheated oven at 350°F (175°C) for 30 minutes.

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

What each ingredient does

Rye flour
Provides the dense, hearty structure and earthy flavour characteristic of this bread.
Cornmeal
Adds a coarse, crumbly texture and bulk to the batter.
Molasses
Adds sweetness, dark colour and moisture, and deepens the flavour.
Sour milk
Its acidity reacts with the baking soda to lift the batter and adds tenderness.
Baking soda
Reacts with the acidic sour milk to produce carbon dioxide, which leavens the bread.

The step that matters

Dissolve the baking soda fully before combining. Baking soda must dissolve evenly in the liquid and react with the sour milk; uneven mixing leaves pockets of bitterness or uneven rise in the finished loaf.
