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

What each ingredient does

Cornmeal
Provides the main body and coarse, crumbly texture of the bread.
Rye meal
Adds a dense, moist crumb and a deeper, earthy flavour.
Wheat flour
Supplies gluten-forming proteins that give the loaf some structure.
Graham flour
Adds bran and coarse particles for a hearty texture and nutty flavour.
New orleans molasses
Adds sweetness, dark colour and moisture, and reacts with baking soda to lift the dough.
Baking soda
Reacts with the acidic molasses to produce gas that leavens the bread.

The step that matters

Adding the foamed molasses and mixing quickly. Baking soda and molasses react immediately to release carbon dioxide. Mixing quickly after the foaming traps that gas in the batter before it escapes, so the bread rises properly.
