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 ↓

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
- Forms the bulk of the bread and gives it its coarse, hearty texture.
- Sour milk
- Its acidity reacts with baking soda to produce gas that lifts the batter.
- Baking soda
- Reacts with the acidic sour milk to produce carbon dioxide, helping the bread rise.
- Molasses
- Adds sweetness, moisture, and the dark color and rich flavor typical of the bread.
- Flour
- Adds some gluten-forming structure to help hold the loaf together.
The step that matters
Steaming for three hours. Steam must be kept steadily supplied so the batter cooks through and rises without drying out. Too little water or heat leaves the loaf dense or underbaked, while the leavening from the baking soda needs moist heat to work well.
