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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Mix and pour
In a large bowl, mix together the Graham flour, cornmeal, molasses, sweet milk, sour milk, and baking soda until well combined.
Pour the mixture into a greased loaf pan.
Steam and bake
Steam the bread for 3 hours.
After steaming, bake in a preheated oven at 350°F (175°C) until the top is brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Graham flour
- Provides the hearty, coarse structure and wheat flavor of the loaf.
- Cornmeal
- Adds a grainy texture and a slightly crumbly crumb.
- Molasses
- Adds sweetness, moisture and the dark brown color.
- Sweet milk
- Adds moisture and hydrates the flours into a batter.
- Sour milk
- Its acidity reacts with the baking soda to help the bread rise.
- Baking soda
- Reacts with the acidic sour milk to release gas that lightens the loaf.
The step that matters
Steam the bread for 3 hours. Steaming keeps the moist batter from drying out while it cooks gently. Gentle, sustained moist heat sets the crumb evenly, so the loaf stays dense and tender rather than dry or cracked.
