Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Hot Water Gingerbread

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.

Make the batter

  1. Add boiling water to molasses.

  2. Mix and sift dry ingredients.

  3. Combine mixtures, add melted butter, and beat vigorously.

Bake

  1. Pour into a buttered shallow pan.

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

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Molasses
Adds sweetness, moisture and deep, dark flavor to the batter.
Baking soda
Reacts with the acidity of the molasses to release gas that lightens the batter.
Flour
Provides structure as its proteins and starches set during baking.
Melted butter
Adds fat that makes the crumb tender and rich.
Ginger
Gives the gingerbread its warm, spicy flavor.

The step that matters

Beat the combined mixture vigorously. Beating blends the wet and dry ingredients into a smooth batter and begins developing gluten in the flour. Beating fully is needed for an even texture, but over-mixing after the flour is fully combined can make the cake tough.

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.
