Why it works: Rye and flour match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,320 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Steamed Brown Bread
Ingredients
Directions
Mix the batter
Dissolve the baking soda in boiling water and add it to the buttermilk.
In a large bowl, combine the rye flour, cornmeal, egg, molasses, and salt.
Pour the buttermilk mixture into the dry ingredients and beat well.
Steam and bake
If steaming in one loaf, steam for 3 hours.
If steaming in one loaf, bake slowly for 30 minutes.
If using two loaves, steam for 2 hours.
If using two loaves, bake for 30 minutes.

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Provides the earthy flavor and a dense, moist structure characteristic of brown bread.
- Cornmeal
- Adds a coarser texture and helps give the loaf its hearty crumb.
- Buttermilk
- Its acidity reacts with the baking soda and adds moisture and tang.
- Baking soda
- Reacts with the acidic buttermilk to release gas, which lightens the loaf.
- Molasses
- Adds sweetness, moisture, and the dark color of the bread.
- Egg
- Binds the ingredients together and adds structure to the batter.
The step that matters
Pour the buttermilk mixture into the dry ingredients and beat well. Baking soda starts reacting with the acid in buttermilk as soon as they meet, releasing gas that lifts the batter. Beating well distributes the soda evenly so the loaf rises uniformly, so the batter should go into the steamer promptly.
