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 says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Mix powdered sugar and warmed butter until smooth.
Add well-beaten eggs and molasses, and mix well.
Stir in flour, fresh-ground ginger, and dissolved baking soda until combined.
Bake
Pour the batter into buttered molds or patty pans.
Bake in a moderate oven at 350°F (175°C) until done.

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 they set in the oven.
- Baking soda
- Reacts with molasses' acidity to release gas, helping the cupcakes rise.
- Flour
- Provides the main structure that holds the cupcakes together as they bake.
- Molasses
- Adds moisture, sweetness, and depth of flavor, and darkens the crumb.
- Butter
- Adds fat for tenderness and richness in the crumb.
The step that matters
Stirring in the dissolved baking soda. Baking soda needs an acid, such as the molasses here, to produce gas for rising. Dissolving it first and mixing it in promptly helps it distribute evenly so the cupcakes rise uniformly rather than in patches.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, butter, egg, molasses, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against sugar, butter, egg, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
