Sour Milk Johnny Cake
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, mix the butter, flour, cornmeal, sugar, baking powder, and salt.
Add the sour milk and beaten eggs, and stir until combined.
Pour the mixture into a well-buttered pan.
Bake
Bake in the preheated oven until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Cornmeal
- Gives the cake its coarse, grainy texture and sturdy crumb.
- All-purpose flour
- Provides the main structure that holds the cake together as it bakes.
- Sour milk
- Adds moisture and acidity that tenderizes the crumb and reacts with the leavener.
- Butter
- Adds fat for flavor and tenderness, and helps the crust brown.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Pour into a well-buttered pan. A thorough coating of butter keeps the cake from sticking and tearing when removed. Baking powder starts releasing gas as soon as it is wet, so the batter should go into the oven promptly.
