Ingredients

Directions

The book says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

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

Make the batter

  1. In a bowl, beat together the butter, sugar, and eggs.

  2. Add the sour cream or buttermilk and baking soda, mixing well.

  3. Gradually stir in the cornmeal and flour until combined.

Bake

  1. Pour the batter into a greased baking dish and bake until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 as they set in the oven.
Baking soda
Reacts with the acidic sour cream or buttermilk to produce gas that lifts the batter.
Sour cream or buttermilk
Adds moisture and acidity, tenderizing the crumb and activating the baking soda.
Cornmeal
Gives the cake its coarse, grainy texture and corn flavor.
Flour
Provides the main structure that holds the cake together as it bakes.
Light brown sugar
Adds sweetness, moisture, and helps the crust brown.

The step that matters

Gradually stir in the cornmeal and flour until combined. Stirring only until combined keeps the batter tender. Overmixing develops gluten in the flour, which can make the cake tough and dense.
