Why it works: Coffee and milk are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,202 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
Boston Brown Bread
Ingredients
Directions
Prepare the batter
Sift together the cornmeal, rye meal, and Graham meal.
In a large bowl, beat together the sifted meals, molasses, sweet milk, sour milk, baking soda, and salt 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.
Boil for four hours, ensuring the water does not boil over or completely evaporate.
After cooking, remove the lid and place the bread in a preheated oven to dry the top for a few moments before serving.

What each ingredient does
- Cornmeal
- Provides the coarse, crumbly body and the characteristic grainy texture of the loaf.
- Rye meal
- Adds a dense, earthy flavour and helps give the loaf its dark, close crumb.
- Graham meal
- Contributes a coarse, nutty texture and wholesome grain flavour to the bread.
- Molasses
- Adds sweetness, dark colour, and moisture, and deepens the bread's flavour.
- Baking soda
- Reacts with the acidic sour milk to produce gas, helping the batter rise and lighten.
- Sour milk
- Its acidity activates the baking soda and tenderises the crumb while adding tang.
The step that matters
Leaving room in the tin for the batter to swell. The baking soda and sour milk reaction makes the batter rise during steaming. A tin filled to the brim can overflow or force the bread to bake heavy and dense, so space must be left before the lid goes on.
