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 cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Grease a 3-quart tin pail.
Make the batter
In a bowl, mix graham flour, cornmeal, sour milk, molasses, and baking soda until well combined.
Pour the batter into the greased pail.
Steam
Cover the pail tightly and place it in a steamer.
Steam for 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Graham flour
- Provides the bulk and wholesome, nutty structure of the bread.
- Cornmeal
- Adds coarse texture and body to the crumb.
- Sour milk
- Its acidity reacts with the baking soda so the bread rises.
- Molasses
- Adds sweetness, dark color, and moisture.
- Baking soda
- Reacts with the sour milk to produce gas that leavens the batter.
The step that matters
Cover the pail tightly. A loose cover lets steam escape, so the pail dries out and the bread may not cook through. A tight seal keeps the steam moist and the heat even during the long steaming.
“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.
