Boston Brown Bread

• Prep Time: 15 minutes

• Cook/Steam Time: 2 hours 15 minutes

• Resting & Cooling Time: 30 minutes

• Total Time: 3 hours

• Yield: 1 large cylindrical loaf (8–10 slices)

• Skill / Intensity Level: Intermediate (requires gentle batter mixing and stove temperature regulation for steaming)

• Heat Intensity: Medium-Low stove heat (constant steady simmer)

Equipment Needed

• Steaming Container: 1 cleaned, empty 28 oz to 30 oz tin can (such as a large baked bean or coffee can) OR a 2-quart pudding mold with a lid.

• Large Stockpot or Dutch Oven: Deep enough to fit the tin can with the lid closed securely.

• Aluminum Foil & Kitchen Twine: To seal the tin can top.

• Wire Rack / Trivet: Placed inside the bottom of the pot to keep the can elevated off direct heat.

Ingredients

Dry Ingredients

• 1 cup (120g) Whole wheat flour

• 1 cup (120g) Rye flour

• 1 cup (150g) Yellow cornmeal (medium or fine grind)

• 2 teaspoons Baking soda

• 1 teaspoon Fine sea salt

Wet Ingredients

• 3/4 cup (255g) Dark unsulfured molasses (or dark strap molasses)

• 2 cups (480ml) Buttermilk (full-fat or low-fat)

Optional Add-in

• 1 cup (150g) Dark or golden raisins (tossed with 1 tablespoon of whole wheat flour to prevent sinking)

Step-by-Step Instructions

Step 1: Prep the Steamer and Mold

1. Grease the inside of your tin can or pudding mold thoroughly with butter or non-stick vegetable cooking spray. Dust lightly with cornmeal or flour, tapping out any excess.

2. Place a heat-proof wire rack, silicone trivet, or extra canning rings at the bottom of a large stockpot or Dutch oven.

3. Fill the pot with about 2 inches of water and place it over medium-high heat to bring the water to a gentle simmer while preparing the batter.

Step 2: Combine Dry Ingredients

1. In a large mixing bowl, whisk together the whole wheat flour, rye flour, yellow cornmeal, baking soda, and fine sea salt until evenly distributed.

2. If adding raisins, toss them in a small bowl with 1 tablespoon of flour until coated, then fold them into the dry flour mixture.

Step 3: Mix the Wet Ingredients & Batter

1. In a medium bowl or liquid measuring cup, combine the dark molasses and buttermilk. Whisk until smooth and completely integrated.

2. Pour the liquid mixture into the dry ingredients.

3. Using a wooden spoon or rubber spatula, gently fold the batter just until the dry ingredients are fully moistened. Do not overmix, as over-activating the gluten will create a rubbery bread rather than a tender crumb.

Step 4: Fill and Seal

1. Scrape the batter into the prepared tin can or mold. It should fill the container about two-thirds of the way up, leaving ample room for the bread to expand as it steams.

2. Cut a square of aluminum foil double-layered with parchment paper. Butter the parchment side and place it face-down over the top of the can.

3. Crimp the foil snugly around the edges of the can. Secure it tightly in place with kitchen twine to prevent moisture and steam condensation from entering the container.

Step 5: Steam the Loaf

1. Carefully lower the sealed tin can onto the rack inside the pot of simmering water. Ensure the water level comes roughly halfway up the sides of the tin can (add more boiling water if necessary).

2. Cover the stockpot tightly with its lid.

3. Adjust the stove intensity to Medium-Low heat to maintain a steady, gentle boil/simmer throughout the steaming process.

4. Steam for 2 hours to 2 hours and 15 minutes. Check the water level periodically every 30 minutes, topping up with boiling water from a kettle if the level drops significantly.

Step 6: Test, Cool, and Unmold

1. Remove the pot lid and carefully extract the hot tin can using oven mitts or tongs.

2. Remove the foil top. Insert a long wooden skewer into the center of the bread; it should come out clean or with a few dry crumbs attached.

3. Let the bread cool upright in the can on a wire rack for 15 to 20 minutes.

4. Run a thin knife around the interior edge of the can. Gently invert the can to slide the warm loaf out onto the cooling rack.

Serving & Preservation

Serving Suggestions

• Classic New England Way: Slice warm rounds using a clean piece of unflavored dental floss or a sharp serrated knife. Serve alongside hot Boston baked beans and grilled franks.

• Toasted with Spread: Slice and toast in a skillet with salted butter, cream cheese, or apple butter.

Storage & Shelf Life

• Room Temperature: Store cooled bread wrapped tightly in plastic wrap or foil for up to 4 days. Steamed bread retains its moisture significantly longer than traditional baked quick breads.

• Refrigeration: Store in an airtight container for up to 1 week.

• Freezing: Wrap slices individually in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw at room temperature or toast directly from frozen.
