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 coarse texture and body, helping the loaf hold together as it steams.
Sour milk
Its acidity reacts with the baking soda to produce gas that lifts the batter.
Molasses
Adds sweetness, moisture, and deep color to the finished bread.
Baking soda
Reacts with the acid in the sour milk to release carbon dioxide, leavening the bread.

The step that matters

Dissolve the baking soda before adding it. Baking soda needs to be fully dissolved so it mixes evenly through the batter. Uneven distribution leaves dense pockets or patches that fail to rise and may taste soapy.
