Boston Brown Bread

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Make the dough

  1. In a large bowl, mix rye flour, corn meal, Graham flour, molasses or brown sugar, and salt.

  2. Stir in warm water until the mixture forms a stiff dough.

  3. Let the dough rise for several hours or overnight.

Rise and bake

  1. When the dough is light, dissolve baking soda in warm water and add it to the mixture.

  2. Beat the dough well and transfer it to well-greased deep bread pans.

  3. Allow the dough to rise again.

  4. Bake in a moderate oven at 350°F (175°C) for 3 to 4 hours.

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

What each ingredient does

Rye flour
Provides the dark, slightly tangy flavour and the body of the loaf.
Corn meal
Adds coarse texture and a sweet corn flavour, keeping the crumb tender.
Molasses or brown sugar
Adds sweetness, dark colour and moisture to the dough.
Homemade yeast
Ferments the dough so it rises and becomes light before baking.
Baking soda
Reacts with the molasses and adds lift, helping the bread rise further in the pan.

The step that matters

Dissolving the baking soda before adding it to the dough. Baking soda must be fully dissolved and mixed evenly through the dough; unevenly distributed soda leaves pockets of bitter flavour and uneven rising. It is added only once the dough is light so its gas release supports the final rise.
