Why it works: Rye and wheat match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 404 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Gives the bread its characteristic flavor and a denser, moist crumb.
- Wheat flour
- Provides gluten for structure, holding the loaf together.
- Cornmeal
- Adds a coarser, slightly crumbly texture to the bread.
- Sour milk
- Its acidity reacts with the baking soda to help the bread rise.
- Molasses
- Adds sweetness, dark color, and moisture.
- Baking soda
- Releases carbon dioxide when it meets the acid in the sour milk, lifting the batter.
The step that matters
Get the batter into the steamer promptly. Baking soda starts reacting with the acid in the sour milk as soon as the batter is mixed. Delaying the move into the steaming dish lets some of that gas escape before the bread sets, which can leave it less light.
