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.

Make the batter

  1. In a large bowl, combine the Indian meal, rye meal, molasses, vinegar, salt, and baking soda.

  2. Gradually add the lukewarm water, mixing until well combined.

Bake

  1. Pour the mixture into a greased baking dish.

  2. Bake in a preheated oven at 350°F (175°C) for 5 hours.

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

What each ingredient does

Indian meal
Forms the bulk of the bread and gives it its coarse, hearty texture.
Rye meal
Adds structure and a dense, earthy flavor to the loaf.
Molasses
Adds sweetness, dark color, and moisture to the bread.
Vinegar
Reacts with the baking soda to help the bread rise.
Baking soda
Produces carbon dioxide gas with the vinegar, lifting the batter as it bakes.

The step that matters

Bake for the full time at a steady, low temperature. Long, gentle baking lets the dense, wet batter set through its center without drying or burning the outside. Because the vinegar and baking soda react as soon as they meet liquid, the batter should go into the oven promptly once mixed.
