Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal (in the method)
- Gives the bread its coarse, dense crumb and hearty texture.
- Sour milk
- Its acidity reacts with baking soda to produce gas, helping the bread rise.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide for lift.
- Molasses
- Adds sweetness, dark colour and moisture to the bread.
- Flour
- Provides structure that holds the dense batter together during steaming.
The step that matters
Steam for 3 hours. Steaming gently cooks the batter while keeping it moist. The pans must be sealed well and the water kept topped up, because without steady steam the bread can dry out or turn out underdone in the centre.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
