Why it works: Molasses and sugar are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Hard Molasses Gingerbread
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, mix together the molasses, sugar, and butter or lard until well combined.
Add the egg and mix until fully incorporated.
Stir in the ginger and salt.
Dissolve the baking soda in a small amount of water and add it to the mixture.
Mix until smooth and pour into a greased baking pan.
Bake
Bake for about 30-40 minutes or until a toothpick comes out clean.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 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
- Provides dark color, moisture, and the characteristic deep sweetness and flavor of gingerbread.
- Butter or lard
- Adds fat for tenderness and a moist, rich crumb.
- Egg
- Binds the batter and adds structure as it sets during baking.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts and lightens the crumb.
- Sugar
- Adds sweetness and helps browning and moisture in the finished cake.
The step that matters
Dissolving the baking soda. Baking soda must be fully dissolved and evenly mixed so it reacts uniformly with the molasses. Clumps can leave bitter, soapy spots and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against molasses, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
