Make the batter

  1. Mix the cornmeal, cream of tartar, sugar, milk, salt, and baking soda in the order given.

  2. Beat thoroughly and then add the sliced apples, mixing well.

Bake

  1. Pour the mixture into a well-buttered shallow cake pan.

  2. Bake for 30 minutes in a hot oven at 400 °F (200 °C).

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

What each ingredient does

White cornmeal
Forms the bulk of the batter and gives the cake its coarse, crumbly texture.
Cream of tartar
Acidic component that reacts with baking soda to help the cake rise.
Baking soda
Alkaline leavener that releases gas with the acid to lift the batter.
Milk
Hydrates the cornmeal and provides moisture for a tender crumb.
Tart apples
Add moisture and a tart flavor that balances the sweetness of the cake.

The step that matters

Mix the cream of tartar and baking soda in the order given. Cream of tartar and baking soda react as soon as they are wet, releasing gas that lifts the batter. Adding them in the stated order and mixing promptly keeps that lift available for the bake.

Swap the apple

How well each one fits the dish's main ingredients (cream, sugar, milk, cinnamon):

  1. Vanillafits better
  2. Raisinfits better
  3. Figfits about as well
  4. Applethe original

Fit is the average pairing score against cream, sugar, milk, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
