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 gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Measure and sift the rye meal, corn meal, graham flour, salt, and baking soda into a bowl.
Add the molasses and sour milk, then beat well until combined.
Pour the mixture into a buttered mold.
Steam and finish
Steam for 3½ hours, ensuring the water in the kettle is boiling and comes halfway up the side of the mold.
Add boiling water as needed to maintain the level.
After steaming, remove the cover and place the mold in a 400°F (200°C) oven for 10 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rye meal
- Adds earthy flavour and a dense, hearty crumb.
- Corn meal
- Gives the bread its coarse texture and body.
- Graham flour
- Adds structure and a nutty, wholesome flavour.
- Baking soda
- Reacts with the sour milk to lift and lighten the batter.
- Molasses
- Adds sweetness, moisture and a deep brown colour.
- Sour milk
- Provides acidity to activate the baking soda and keeps the crumb moist.
The step that matters
Keeping the steaming water boiling and at the right level. If the water stops boiling or drops below the mold's halfway point, steam weakens and the bread cooks unevenly and turns heavy. Adding boiling water keeps the heat and steam steady throughout the long steam.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
