Why it works: Milk and flour 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
- Cornmeal
- Provides the coarse, crumbly body that gives this bread its texture.
- Graham flour
- Adds structure and a nutty, wholesome flavor to the batter.
- Molasses
- Adds sweetness, dark color, and moisture to the bread.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
- Sour milk
- Supplies moisture and acidity that activates the baking soda.
The step that matters
Cover the container tightly. Steaming relies on trapped moisture to cook the batter evenly. A loose cover lets steam escape, which can leave the bread dry or underdone.
