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

What each ingredient does

Yeast: Produces gas as it works, lifting the batter so it rises and cracks on top.
Indian meal: Forms the coarse, crumbly body of the bread.
Rye: Adds structure and a dense, hearty texture with a earthy flavor.
Molasses: Adds sweetness, dark color, and moisture.
Sour milk: Its acidity reacts with the soda and softens the bread crumbs.
Soda: Leavens the bread by reacting with the acidic sour milk to create gas.

The step that matters

Warm rising of the batter. Yeast works slowly in cool conditions, so the batter needs a warm place to rise. Judging when it cracks over the top shows that gas has built up enough for a light, well-risen loaf.
