Johnny Cake

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 400°F (200°C).

  2. Sift together the cornmeal, flour, salt, sugar, and baking powder.

  3. Melt the butter and lard in a baking pan.

  4. Pour the melted mixture over the sifted ingredients and mix lightly with your fingertips.

Bake

  1. Stir in the sour milk and beaten egg.

  2. Pour the batter into the hot pan and bake until golden.

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 the characteristic coarse, grainy texture.
Flour
Adds structure so the batter holds together while baking.
Egg
Binds the batter and adds richness and structure as it sets.
Sour milk
Adds moisture and tang, and reacts with the baking powder to help the cake rise.
Butter
Adds fat for richness, tenderness and flavor.
Baking powder
Releases gas in the batter to lift it as it bakes.

The step that matters

Pour the batter into the hot pan. The pan must be hot when the batter goes in, so the outside begins to set and brown immediately. This gives a crisp crust and helps the cake rise evenly instead of spreading and sticking.
