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 molasses acidity to produce gas, helping the bread rise.
Molasses
Adds sweetness, dark colour and moisture, and its acidity activates the baking soda.
Milk
Hydrates the flours so the batter forms a moist, pourable mixture.
White flour
Provides gluten-forming structure to hold the bread together.
Graham flour
Adds coarse texture and a nutty, wholesome flavour to the bread.
Indian meal
Adds cornmeal texture and body, giving the bread its characteristic crumb.

The step that matters

Keeping the steamer sealed and water out. Steaming cooks the bread gently with moist heat over a long time. If the lid is loose or water enters, the bread can turn soggy and uneven, so the seal must stay tight throughout the three hours.
