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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
In a large bowl, combine cornmeal, flour, sour milk, sweet milk, molasses, baking soda, and salt, and mix until well combined.
Pour the mixture into a greased steaming mold.
Steam and brown
Steam for 3 hours.
After steaming, place the mold in a preheated oven at 400°F (200°C) to brown.

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
- Cornmeal
- Provides the coarse, crumbly body that gives the bread its structure.
- All-purpose flour
- Adds gluten-forming structure so the bread holds together after steaming.
- Sour milk
- Its acidity reacts with the baking soda to produce gas that lifts the batter.
- Molasses
- Adds sweetness, moisture, and the dark color typical of this bread.
- Baking soda
- Reacts with the acid in sour milk to leaven the batter.
The step that matters
Pour the batter into the mold promptly. Baking soda starts reacting with the acid in sour milk as soon as it is mixed. Getting the batter into the mold and steaming without delay keeps that gas inside the batter to lift it, rather than losing it while the batter sits.
“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.
