What exactly is “brown bread in a can,” and what are its defining characteristics?
Brown bread in a can is a traditional New England food item, typically a sweet, steamed bread made with a combination of cornmeal, rye flour, and wheat flour. It’s distinctively baked (actually, steamed) directly inside a cylindrical can, resulting in its signature shape and moist texture. Molasses or brown sugar gives it its characteristic dark color and sweet flavor, often complemented by additions like raisins.
The appeal of canned brown bread lies in its convenience and long shelf life. It’s shelf-stable due to the canning process, requiring no refrigeration until opened. When ready to eat, it’s usually sliced and served warm, often with butter, cream cheese, or as a side to baked beans. The unique slightly dense, almost pudding-like texture and subtly sweet taste make it a distinctive culinary experience.
How is brown bread actually cooked inside a can?
The cooking process is a form of steaming that occurs entirely within the sealed can. The batter, consisting of the flours, molasses, leavening agent (usually baking soda), and water, is poured into the can, leaving some headspace at the top. The can is then sealed and placed in a large pressure cooker or steamer, where it’s exposed to high temperatures for an extended period, typically several hours.
The heat causes the batter to rise and cook thoroughly. The steam circulating around the can transfers heat evenly, ensuring the bread bakes consistently. The sealing of the can prevents moisture from escaping, leading to the characteristic moistness of the final product. After the cooking time is complete, the cans are cooled, and the bread is ready for consumption or storage.
What ingredients are typically found in canned brown bread, and what purpose do they serve?
