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 ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Graham flour
- Provides the bulk and structure of the loaf, with a coarse, hearty texture.
- Cornmeal
- Adds body and a dense, crumbly texture to the crumb.
- Molasses
- Adds sweetness, moisture, and deep color, and its acidity reacts with the baking soda.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts and lightens the batter.
- Sweet milk
- Hydrates the flours and keeps the loaf moist during cooking.
The step that matters
Pour the batter into the pan and get it steaming promptly. Baking soda starts reacting as soon as it meets the acidic molasses and liquid. Delaying the pan and steamer lets some of that rising power escape, which can leave the loaf denser.
