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. In a large bowl, combine the wheat flour, corn meal, and Graham flour.

  2. Add the molasses, baking soda, salt, lard, sour milk, and enough water to form a stiff sponge.

  3. Pour the mixture into brown bread tins.

Steam and bake

  1. Steam the tins for 2 hours.

  2. Remove from the steamer and bake in a 350°F (175°C) oven for 10 minutes.

Serve

  1. Take the bread out of the tins and serve hot.

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

What each ingredient does

Wheat flour
Provides the main structure that holds the loaf together as it steams.
Corn meal
Adds a coarse, crumbly texture and a slightly gritty bite to the loaf.
Graham flour
Contributes a nutty flavour and a denser, more textured crumb.
New orleans molasses
Adds moisture, dark colour and a deep, sweet, slightly bitter flavour.
Baking soda
Reacts with the acidic sour milk to produce gas that lightens the batter.
Sour milk
Its acidity activates the baking soda and tenderises the crumb while adding moisture.

The step that matters

Keeping the tins covered and steaming gently. Steam cooks the batter slowly and keeps it moist; if water boils dry or the tins are left uncovered, the loaf dries out and may not set evenly through the centre.
