Washington Cake

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. Preheat the oven to 350°F (175°C).

  2. In a bowl, mix the yolk of one egg, sugar, molasses, and melted butter.

  3. Add cinnamon, cloves, sour milk, and baking soda; mix well.

  4. Gradually stir in the flour until combined.

Bake and frost

  1. Divide the batter into three layers and bake until golden.

  2. Whip the egg white and use it to frost the cake.

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

What each ingredient does

Egg yolk
Adds richness and helps bind the batter together.
Molasses
Adds dark color, moisture, and a deep sweet flavor.
Sour milk
Its acidity reacts with the baking soda to lighten the crumb.
Baking soda
Reacts with the acid in sour milk to produce gas that makes the cake rise.
Flour
Provides the structure that sets the cake as it bakes.
Egg white
Whipped, it forms a light frosting that sets on the cake.

The step that matters

Gradually stir in the flour until combined. Overmixing once flour is added develops gluten, which can make the cake tough and dense. Stirring just until combined keeps the crumb tender.

Swap the clove

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

  1. Nutmegfits better
  2. Cardamomfits about as well
  3. Clovethe original
  4. Allspicefits about as well

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