Why it works: Flour and milk are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boston Brown Bread
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
In a large bowl, mix graham flour, cornmeal, salt, molasses, sour milk, hot water, and cold water.
Dissolve the baking soda in the hot water before adding it to the mixture.
Steam or bake
Divide the batter into four one-pound baking powder cans with tightly fitting covers.
Steam the cans for 3 hours or bake in a 300°F (150°C) oven for 1.5 hours.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Flour and milk barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Graham flour
- Provides the main structure and the coarse, hearty body of the bread.
- Cornmeal
- Adds a grainy texture and helps the loaf hold a crumbly, moist crumb.
- Molasses
- Adds sweetness, moisture, and the dark color typical of this bread.
- Sour milk
- Its acidity reacts with baking soda, producing gas that helps the bread rise.
- Baking soda
- Reacts with the acid in sour milk to leaven the batter.
The step that matters
Dissolve the baking soda in the hot water first. Baking soda must be evenly dispersed to react with the acid in the sour milk. Dissolving it first spreads the reaction through the batter, giving an even rise and avoiding pockets of bitter soda or dense spots.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
