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.

Prepare the batter

Mix the cornmeal, wheat flour, cornstarch, salt, and enough water to wet thoroughly in a bowl. Milk can be used instead of water.
In the morning, add the egg, baking soda, brown sugar, and melted butter to the mixture. Beat well.

Bake

Bake immediately in a preheated oven at 350°F (175°C) until golden.

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

What each ingredient does

Fine yellow cornmeal: Forms the main body of the cake, giving it its grainy texture and corn flavor.
Wheat flour: Adds gluten-based structure that helps hold the cake together.
Egg: Binds the batter and adds structure and richness as it sets.
Baking soda: Reacts with the batter to produce gas, helping the cake rise and lighten.
Brown sugar: Adds sweetness and moisture, and helps the crust brown.
Melted butter: Adds fat for tenderness, moisture, and rich flavor.

The step that matters

Bake immediately after adding the baking soda. Baking soda starts releasing gas as soon as it meets the liquid and acid-free batter, so waiting lets the gas escape and reduces rise. Baking promptly keeps the lift in the cake.
