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 ↓
Rye Bread
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Mix the rye meal, cornmeal, flour, and salt in a bowl.
Dissolve the baking soda in 2 tablespoons of boiling water.
Add the dissolved soda and sour milk to the molasses and stir well.
Pour this mixture into the dry ingredients and mix thoroughly.
Beat the egg and add it to the mixture, stirring until well combined.
Pour the batter into a well-buttered 2-quart tin pan.
Steam and bake
Steam the bread for 2 hours, then bake in a preheated oven at 350°F (175°C) for 30 minutes.

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Molasses
- Adds sweetness, moisture, and a dark color and deep flavor to the bread.
- Sour milk
- Its acidity reacts with the baking soda to lift the batter and adds moisture.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that makes the bread rise.
- Egg
- Binds the batter and helps it set into a cohesive crumb.
- All-purpose flour
- Provides structure so the batter holds its shape as it cooks.
- Cornmeal
- Gives the bread a coarse, slightly crumbly texture.
The step that matters
Steam the bread for 2 hours. Steaming keeps the moist, leavened batter from drying out while it sets, so the bread stays tender. Steam needs to stay sealed and the water must not boil dry, or the loaf can dry out and set unevenly.
