Why it works: Rye and milk work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 918 recipes. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
Boston Brown 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.
Prepare the batter
Combine cornmeal, rye meal, sour milk, molasses, baking soda, and salt in a large bowl, then mix until well combined.
Pour the mixture into a greased steaming mold.
Steam and bake
Steam for 4 hours.
Bake in a preheated oven at 350°F (175°C) for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Provides the main body and coarse, crumbly structure of the bread.
- Rye meal
- Adds a denser texture and a deeper, earthy flavor.
- Sour milk
- Supplies moisture and acid that reacts with the baking soda to lift the bread.
- Molasses
- Adds sweetness, moisture, and the dark color typical of this bread.
- Baking soda
- Reacts with the acid in sour milk to produce gas that makes the bread rise.
The step that matters
Mix the batter until just combined, then steam promptly. Baking soda starts reacting as soon as it meets the acidic sour milk, so gas forms quickly. Delaying the pour into the mold lets some of that lift escape before the batter sets.
