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 ↓
Molasses 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. 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, lard, and butter until well combined.
Add the cold water and stir until smooth.
Mix in the baking soda and ginger.
Gradually add flour until a dough forms.
Bake
Transfer the dough to a greased baking pan and bake for about 30-40 minutes or until a toothpick comes out clean.

Butter and flour 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
- Provides dark color, moisture and a deep, slightly bitter sweetness.
- Sugar
- Adds sweetness and helps the cake brown and stay tender.
- Lard
- Adds fat that keeps the crumb tender and moist.
- Butter
- Adds fat and flavor, contributing richness to the crumb.
- Baking soda
- Reacts with the acidic molasses to release gas, helping the cake rise.
- Flour
- Provides the structure that sets the cake as it bakes.
The step that matters
Mixing in the baking soda. Baking soda needs an acid, such as molasses, to release carbon dioxide. Adding it to the wet mixture and then working in flour without delay helps the cake rise evenly rather than collapsing or staying flat.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against molasses, sugar, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
