Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a bowl, combine buttermilk and baking soda, and stir until dissolved.
Add cornmeal and flour, and beat thoroughly.
Bake
Pour the batter into a well-greased pan.
Bake for 20 minutes.

What each ingredient does
- Buttermilk
- Provides acidity that reacts with baking soda and adds moisture and tang.
- Baking soda
- Reacts with the acidic buttermilk to release carbon dioxide, which makes the bread rise.
- Cornmeal
- Gives the bread its coarse, grainy structure and corn flavor.
- Flour
- Adds gluten-forming protein that gives the batter structure and holds its shape.
The step that matters
Stir the buttermilk and baking soda until dissolved, then add the batter ingredients promptly. Baking soda starts reacting as soon as it meets the acid in buttermilk, releasing gas. Delaying the batter and baking lets that gas escape, so the cake may rise less.
