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 ↓

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 whole-grain body of the bread.
- Cornmeal
- Adds a coarse, crumbly texture and a grainy bite.
- Molasses
- Adds sweetness, moisture, and the dark brown color.
- Sour milk
- Its acidity reacts with the baking soda to help the bread rise.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lightens the batter.
The step that matters
Keep the pan tightly covered while it steams. A tight cover traps steam around the batter so it cooks evenly and stays moist. Steady boiling keeps that steam supplied for the full 4 hours, so the bread sets without drying out.
