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.

Mix the batter

  1. Add the boiling water to the molasses.

  2. Mix and sift the dry ingredients together.

  3. Combine the wet and dry mixtures.

  4. Add the melted butter and beat vigorously.

Bake

  1. Pour the batter into a buttered shallow pan.

  2. Bake for 25 minutes at 350°F (175°C).

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

What each ingredient does

Molasses
Provides sweetness, dark colour, moisture and the characteristic gingerbread flavour.
Baking soda
Reacts with the acidic molasses to produce gas that lifts the batter and darkens it.
Flour
Builds the structure that holds the batter's shape as it bakes.
Melted butter
Adds fat for tenderness and a rich mouthfeel.
Ginger
Contributes the warm, spicy aroma that defines the cake.

The step that matters

Beat the batter vigorously after adding the butter. Vigorous beating develops gluten in the flour, which can make the gingerbread tough and dense. Stop once the batter is smooth and evenly combined.

Swap the ginger

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

  1. Cinnamonfits better
  2. Jalapenofits better
  3. Nutmegfits better
  4. Gingerthe original

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