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
Provides the coarse body and texture that holds the loaf together.
Sour milk
Its acidity reacts with the baking soda to lift the batter and add tang.
Molasses
Adds sweetness, dark color and moisture.
Baking soda
Reacts with the acidic sour milk to produce gas that makes the bread rise.

The step that matters

Dissolving the baking soda before adding it. Baking soda must be fully dissolved and mixed evenly into the batter so it reacts with the sour milk throughout. Uneven mixing leaves pockets of soda that can taste bitter and leaves dense or patchy rising.
