Aunt Rachel's Molasses Cake

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

Make the batter

  1. In a bowl, cream together the butter and hot water.

  2. Add the baking soda and molasses, mixing well.

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

  4. Pour the batter into a greased baking pan.

Bake

  1. Bake for about 30-40 minutes or until a toothpick comes out clean.

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

What each ingredient does

Flour
Provides the structure that sets the cake's crumb as the batter bakes.
Molasses
Adds moisture, sweetness and a dark color to the cake.
Baking soda
Reacts with the molasses's acidity to produce gas that lifts the batter.
Butter
Adds fat that contributes tenderness and richness to the crumb.

The step that matters

Adding the baking soda and molasses. Baking soda needs an acid to react and release gas for rising; molasses supplies that acidity, so the soda should be mixed in thoroughly and the batter baked promptly to keep the lift.

Swap the allspice

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

  1. Nutmegfits better
  2. Allspicethe original
  3. Cardamomfits less well
  4. Gingerfits less well

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