Johnny Cake

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the cornmeal, flour, sugar, salt, and baking powder.

  3. In another bowl, beat the egg and add the milk.

Make and bake

  1. Combine the wet and dry ingredients until just mixed.

  2. Pour the batter into a greased baking dish.

  3. Bake for 25-30 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Provides the main structure that holds the batter together as it bakes.
Cornmeal
Gives the cake its coarse, grainy texture and golden colour.
Egg
Binds the batter and adds structure and richness.
Baking powder
Releases gas in the batter so the cake rises and becomes light.
Milk
Hydrates the dry ingredients and adds moisture to the batter.
Sugar
Adds sweetness and helps the crust brown as it bakes.

The step that matters

Combine the wet and dry ingredients until just mixed. Overmixing develops gluten in the flour, which makes the cake tough and dense. Stir only until no dry streaks remain, leaving small lumps.
