What each ingredient does

Rye meal
Gives the loaf its dense, hearty structure and its characteristic earthy flavour.
Indian meal
Provides the coarse body and crumb that holds the steamed loaf together.
Sour milk
Its acidity reacts with the baking soda to lift the batter and adds tang.
Molasses
Adds sweetness, dark colour and moisture to the finished bread.
Baking soda
Reacts with the acidic sour milk to release gas, which leavens the batter.

The step that matters

Dissolve baking soda in hot water before adding. Dissolving the soda evenly prevents pockets of bitter, unreacted soda and spreads the leavening reaction through the batter so the loaf rises uniformly.
