Boston Brown Bread

Ingredients

Directions

Prepare the batter

Sift together the cornmeal, rye meal, and Graham meal.
Beat together the sifted meals, molasses, sweet milk, sour milk, baking soda, and salt in a large bowl until well combined.
Pour the mixture into a tin form or a covered tin pail, leaving room for it to swell.

Steam and finish

Place the form in a kettle of cold water and bring to a boil.
Cook for 4 hours.
Ensure the water does not boil over the top of the form and does not completely evaporate.
After cooking, remove the lid and place the bread in a warm oven for a few minutes to dry the top before turning it out.

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

What each ingredient does

Cornmeal: Gives the loaf its coarse, crumbly structure and characteristic grainy texture.
Rye meal: Adds a dense body and a deeper, earthy flavor to the crumb.
Graham meal: Contributes a coarse, nutty texture and wholesome flavor to the loaf.
Molasses: Provides sweetness, moisture, and the dark color typical of this bread.
Baking soda: Reacts with the sour milk's acidity to produce gas, lifting and lightening the loaf.
Sour milk: Its acidity activates the baking soda and adds tang and tenderness.

The step that matters

Keeping the water level right during the long steam. The form must stay submerged enough to keep the bread cooking evenly, but the water must not boil over into the form. Steady, gentle simmering prevents a soggy top or a dry, unevenly cooked loaf over the four-hour steam.
