Why it works: Sugar and molasses 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 ↓

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 the batter
Preheat oven to 350°F (175°C).
In a large bowl, cream butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in molasses and mix until combined.
Dissolve baking soda in a small amount of warm water and add to mixture.
Add ginger to taste.
Gradually add flour until batter is as thick as pound cake.
Bake
Pour batter into greased cake pan and bake for about 45‑50 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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Adds richness and tenderness through fat coating the flour and trapping air when creamed.
- Sugar
- Creams with the butter to trap air and adds sweetness and browning.
- Molasses
- Adds moisture, deep flavour, and dark colour to the cake.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
- Flour
- Forms the structure of the cake once mixed with the liquids and eggs.
The step that matters
Dissolving the baking soda. Baking soda must be fully dissolved in warm water before it is added so it reacts evenly with the acidic molasses. Clumps can leave bitter spots and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against egg, sugar, molasses, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
