Why it works: Flour and molasses are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 10,429 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Boston 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
In a large bowl, combine cornmeal, flour, molasses, warm water, vinegar, baking soda, and salt. Mix well until smooth.
Cook and bake
Transfer the mixture to a pot and boil for four hours.
After boiling, pour the mixture into a baking dish and bake for two hours at 350°F (175°C).
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cornmeal
- Forms the main body of the bread and gives it its coarse, hearty texture.
- Flour
- Adds structure so the cornmeal mass holds together after cooking.
- Molasses
- Adds sweetness, dark color and moisture, and helps the crust brown.
- Baking soda
- Reacts with the acid in the vinegar to produce gas that lifts the bread.
- Vinegar
- Provides acid that reacts with the baking soda to help the bread rise.
The step that matters
Boiling the batter for four hours. Long, steady boiling keeps the thick batter moist and fully cooks the cornmeal starch, so the bread sets evenly before baking. Stirring or lowering the heat too much can scorch the bottom or leave the texture uneven.
