Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rye meal
Gives the bread its dense, hearty structure and earthy flavor.
Indian meal
Adds body and coarse texture, giving the loaf its characteristic crumb.
Sour milk
Its acidity reacts with the baking soda to produce gas that lightens the batter.
Molasses
Adds sweetness, dark color, and moisture to the loaf.
Baking soda
Reacts with the acid in the sour milk to make the bread rise.

The step that matters

Dissolve the baking soda fully before adding it. Baking soda must be evenly dissolved and mixed through the batter so it reacts with the acidic sour milk throughout. Unmixed pockets can leave bitter spots or uneven rising.
