Why it works: Rye and corn work together. They rank in the top 7% of all ingredient pairs, and cooks put them together in 182 recipes. Both carry acetic acid, which smells sour, vinegar. The science ↓
Boston Brown Bread
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Mix the rye flour, cornmeal, all-purpose flour, molasses (or sugar), and salt thoroughly in a bowl.
Wet the mixture with sour milk until it forms a thick batter.
Dissolve the baking soda in a tablespoon of water and add it to the batter.
Stir the batter until it is as thick as possible, mixing with a spoon.
Bake
Pour the batter into well-greased pans.
Bake in a moderate oven at 350°F (175°C) for about 3 to 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye flour
- Adds a dense, earthy flavor and structure to the dark, sturdy crumb.
- Corn meal
- Gives the bread its coarse, grainy texture and body.
- All-purpose flour
- Provides gluten structure so the batter holds together while baking.
- Molasses or brown sugar
- Adds sweetness, moisture, and the bread's dark color.
- Baking soda
- Reacts with the acidic sour milk to produce gas that lifts the batter.
The step that matters
Stir the batter until as thick as possible. A very thick batter holds the gas from the baking soda and sour milk reaction, helping the bread rise instead of spreading and turning out heavy. Thin batter loses lift.
