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 Without Shortening
Ingredients
Directions
Make the batter
Bring 1 cup of molasses to a boil.
Stir in 1 tablespoon of baking soda and pour it over 1 cup of sugar, 1 egg, and 1 tablespoon of ginger while it is foaming.
Add 1 tablespoon of vinegar and enough flour to make a stiff batter.
If the batter is too runny, add more flour to make it stiffer.
Bake and serve
Bake and test a few first to ensure they hold their shape.

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, sweet flavor.
- Baking soda
- Reacts with the acidic molasses and vinegar to produce gas, helping the cake rise.
- Egg
- Adds structure and binds the batter together as it sets.
- Flour
- Provides the structure that makes the batter stiff enough to hold its shape.
- Vinegar
- Adds acidity that reacts with the baking soda to help the cake rise.
The step that matters
Stir in the baking soda while the molasses is foaming. Baking soda reacts with the acidic molasses and vinegar to release gas. Adding it at the right moment and mixing promptly lets that gas be trapped in the batter, so the cake rises well. Waiting too long lets the reaction fade.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, egg, vinegar, flour):
- Cinnamonfits better
- Jalapenofits better
- Nutmegfits about as well
- Gingerthe original
Fit is the average pairing score against molasses, sugar, egg, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
