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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking soda
- Reacts with the sour milk to produce gas, so the bread rises and turns light.
- Sour milk
- Its acidity activates the baking soda and adds moisture to the batter.
- Molasses
- Adds sweetness, dark color, and moisture to the bread.
- Cornmeal
- Gives the bread a coarse, crumbly texture and body.
- Graham flour
- Provides the structure and the nutty, whole-grain flavor of the bread.
The step that matters
Steaming time. Steaming gently cooks the batter through without drying it. Steaming for too short a time leaves the centre gummy, while the right time sets the crumb. The 1 to 3 hour range depends on mold size, so check the bread is set in the centre before removing it.
