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
- Flour
- Provides the structure that holds the loaf together as it sets.
- Cornmeal
- Gives the bread its coarse, dense texture and body.
- Molasses
- Adds sweetness, dark colour and moisture to the crumb.
- Baking soda
- Reacts with the acidity in the batter to produce gas that lifts the bread.
- Baking powder
- Provides extra rising power so the loaf lightens during steaming.
- Eggs
- Bind the batter and help set the structure of the loaf.
The step that matters
Steam for 5 hours. Steam must stay steady and the mold must be sealed so water does not enter. Gentle, continuous heat sets the batter evenly without drying the loaf, and a long steam time is needed for a fully cooked centre.
