This steamed bread combines rye flour and fine cornmeal for a hearty texture that feels substantial without becoming heavy.
Raisins add little pockets of fruity sweetness, while buttermilk brings gentle tang and helps create the bread’s soft, moist crumb.
Unlike traditional baked loaves, this recipe is steamed in cans, producing its characteristic shape and wonderfully tender texture.
The preparation is surprisingly simple, requiring just a handful of ingredients and a few basic kitchen tools.
The batter comes together quickly by combining the dry ingredients with buttermilk and molasses before being portioned into prepared cans.
As the loaves gently steam, they become firm while remaining pleasantly moist inside, with a skewer revealing tender crumbs when they are ready.
Once cooled, the bread can be served plain or toasted, making it flexible enough for breakfast, an afternoon snack, or a comforting side.
Cream cheese makes an especially appealing accompaniment, adding a creamy contrast to the bread’s rich molasses flavor and chewy raisins.
For the best flavor, the finished loaves are preferably rested until the following day, allowing the flavors to meld and develop further.
With its rustic appearance, distinctive rye-and-cornmeal character, and sweet molasses finish, this Boston brown bread is a memorable homemade treat that is both practical and satisfying.
Classic Boston Brown Bread
Ingredients
Equipment
Method
- Prepare the Steaming Pot: Place a trivet or steamer insert in the bottom of a tall stockpot and add enough water to reach 1 1/2 inches above the trivet. Cover the pot tightly and bring the water to a simmer over medium-high heat.
- Prepare the Cans: Coat three 14.5- to 15-ounce cans, approximately 4 inches tall and 2 3/4 inches wide, with cooking spray. Place a round piece of parchment paper in the bottom of each can.
- Combine the Dry Ingredients: In a medium bowl, whisk together the rye flour, raisins, fine cornmeal, baking soda, and kosher salt until the ingredients are evenly distributed.
- Make the Batter: Add the buttermilk and blackstrap molasses to the dry mixture and whisk just until everything is combined. Avoid overmixing.
- Fill the Cans: Divide the batter evenly among the three prepared cans, using about 1 cup (200 g) of batter per can. Make sure the batter fills each can no more than two-thirds full.
- Cover the Cans: Place a small square of foil over the top of each filled can to create a lid, then secure the foil firmly with a heavy-duty rubber band or string.
- Position the Cans: Carefully place the covered cans upright on the trivet inside the pot. The water should reach approximately halfway up the sides of the cans; if it does not, add additional hot water.
- Steam the Bread: Cover the stockpot and return the water to a simmer over medium-high heat. Reduce the heat to medium-low and gently simmer the cans for 35 to 40 minutes.
- Check for Doneness: The bread is ready when it is set and gently pulling away from the sides of the cans. A skewer inserted into the center should come out with moist crumbs, while a thermometer inserted into the center should register between 200°F and 205°F.
- Remove and Cool: Using tongs, carefully remove the cans from the pot and place them on a cooling rack.Remove the foil lids and allow the bread to cool in the cans for 20 to 30 minutes.
- Release the Loaves: Turn each can upside down and tap the bottom with the heel of your palm to release the bread. Transfer the loaves to a wire rack.
- Cool Completely: Let the loaves cool completely on the wire rack for about 1 hour before serving.
- Serve and Rest: Serve the bread plain or toasted with cream cheese. For the best flavor, preferably allow the cooled loaves to rest until the next day so the flavors can meld and improve.
Notes
- Use three 14.5- to 15-ounce cans that are approximately 4 inches tall and 2 3/4 inches wide for the intended loaf size.
- Coat the cans thoroughly with cooking spray and line their bottoms with parchment to help the steamed bread release cleanly.
- Keep the batter level below two-thirds of each can so there is enough room for the bread to set properly.
- Make sure the steaming water reaches about halfway up the sides of the cans during cooking.
- The finished bread should be set and gently pulling away from the can sides, with moist crumbs clinging to a skewer.
- For table salt, use half the volume specified for Diamond Crystal kosher salt.
- Allow the bread to cool completely before serving for the best texture.
- Resting the cooled loaves until the next day allows the flavors to meld and improve.
Chef’s Secret
The most important detail for getting the characteristic moist texture of Boston brown bread is maintaining the proper steaming environment throughout cooking.
After placing the covered cans on the trivet, check that the water reaches about halfway up their sides, adding additional hot water if necessary.
Keep the stockpot tightly covered so the steam remains trapped, then reduce the heat to medium-low once the water returns to a simmer.
Avoid removing the lid unnecessarily because escaping steam can affect the cooking process.
When checking the loaves, look for bread that has set and begun gently pulling away from the can sides rather than waiting for a completely dry skewer.
The center should still produce moist crumbs, which helps preserve the bread’s signature tender texture.
Serving Suggestions
Serve Boston brown bread plain for a simple taste of its rich rye, cornmeal, and molasses flavors, or toast slices lightly for a warmer, more developed finish.
Cream cheese makes a natural accompaniment and provides a cool, creamy contrast to the sweet, hearty bread.
Sliced loaves can also be served as part of a breakfast or snack spread alongside other simple favorites.
Because the recipe specifically recommends resting the bread until the following day, prepare it ahead when possible and slice it once completely cooled for serving.
Conclusion
This Boston brown bread delivers a moist, tender crumb with hearty rye, sweet raisins, and deep blackstrap molasses flavor.
Its distinctive steamed preparation creates a wonderfully soft texture while keeping the recipe straightforward.
Serve it plain or toasted with cream cheese, and allow the finished loaves to rest overnight when possible for even better flavor.
