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 Drop Cakes
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat your oven to 350°F (175°C).
In a large bowl, mix together the molasses, melted butter, and sugar.
Dissolve the baking soda in the hot water and add it to the mixture.
Beat in the egg, ginger, and salt until well combined.
Gradually add the flour, mixing until smooth.
Bake
Drop spoonfuls of the batter onto a greased baking sheet.
Bake for 10-12 minutes or until golden brown.

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
- Adds deep sweetness, dark color and moisture to the batter.
- Baking soda
- Reacts with the molasses' acidity to produce gas that lifts the cakes.
- Flour
- Provides the structure that holds the cakes together as they set.
- Butter
- Adds richness and tenderness, and helps keep the cakes moist.
- Egg
- Binds the batter and helps give the cakes structure as they set.
The step that matters
Dissolving the baking soda in the hot water. Baking soda must be fully dissolved so it reacts evenly with the molasses' acidity. Undissolved pockets can cause uneven rising and bitter spots in the cakes.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, sugar, egg, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
