Why it works: Rye and milk work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 918 recipes. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓

What each ingredient does
- Rye meal
- Gives the loaf its dense, hearty structure and earthy flavor.
- Indian meal
- Adds coarse texture and body that holds the loaf together.
- Sour milk
- Its acidity reacts with the baking soda to lift the batter.
- Molasses
- Adds sweetness, dark color, and moisture to the bread.
- Baking soda
- Reacts with the sour milk acid to produce gas that makes the bread rise.
The step that matters
Dissolve the baking soda before adding it. Baking soda must be fully dissolved in hot water so it spreads evenly through the batter. Undissolved pockets can leave bitter, unevenly risen spots, and the reaction with the sour milk's acid gives the loaf its lift.
