Why it works: Barley and rye share more aroma than cooks usually use. They rank in the top 4% of all ingredient pairs, and cooks put them together in 66 recipes. Both carry isoamyl acetate, which smells banana, pear. The science ↓
Steamed Brown Bread
Ingredients
Directions
Prepare
Sift together cornmeal, barley flour, rye flour, baking powder, salt, and ginger.
Dissolve baking soda in a little cold water.
Add the dissolved baking soda to the sour milk.
Mix and steam
Combine the liquid with the dry ingredients.
Beat the mixture well.
Steam in a well-greased brown bread tin or baking powder cans for 5 to 6 hours, depending on the size of the tin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with the baking soda, producing gas that helps the bread rise.
- Baking soda
- Reacts with the acid in the sour milk and molasses to lift the batter as it steams.
- Baking powder
- Provides additional lift so the batter rises during steaming.
- Molasses
- Adds sweetness, dark color, and moisture to the bread.
- Rye flour
- Adds flavor and a dense, moist crumb along with the barley flour.
- Cornmeal
- Gives the bread a coarse, tender texture and a grainy body.
The step that matters
Dissolve the baking soda and add it to the sour milk before combining. Baking soda needs an acid to release gas. Dissolving it evenly in the sour milk spreads the reaction through the batter so the bread rises uniformly rather than in pockets.
Swap the ginger
How well each one fits the dish's main ingredients (barley, flour, rye, molasses, milk):
- Cinnamonfits better
- Nutmegfits better
- Clovefits better
- Gingerthe original
Fit is the average pairing score against barley, flour, rye, molasses, milk. Candidates are from the same food group and used in at least 100 recipes.
