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.

Make the batter

  1. Pour boiling water over the cornmeal and stir.

  2. Add sugar and pumpkin.

  3. Mix in sour milk with dissolved baking soda.

  4. Sift flour with baking powder and add to the mixture.

  5. Incorporate beaten eggs and seasoning.

  6. Beat briskly, then pour into a buttered tin.

Bake

  1. Bake at 350°F (175°C) until done.

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 grainy texture of the cake.
Baking soda
Reacts with the sour milk to produce gas, helping the cake rise.
Baking powder
Adds additional lift so the batter rises during baking.
Eggs
Bind the batter and add structure and richness as they set.
Pumpkin
Adds moisture and softness to the crumb.
Sour milk
Its acidity activates the baking soda and tenderises the crumb.

The step that matters

Adding the baking soda to the sour milk. Baking soda needs an acid to release carbon dioxide. Dissolving it fully in the sour milk and then mixing promptly lets the gas form in the batter, so the cake rises well. Letting the batter stand too long loses this lift.

Swap the pumpkin

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