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.
Make the dough
In a bowl, mix together the sugar, molasses, butter, and strong coffee.
Add the ginger, baking soda, and salt.
Gradually add flour until the dough is manageable for rolling out.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in a preheated oven at 350°F (175°C) until golden.

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
- Sugar
- Adds sweetness and helps the cookies brown as they bake.
- Molasses
- Adds moisture, deep flavor, and dark color, and reacts with the baking soda.
- Butter
- Adds fat for richness and a tender texture.
- Baking soda
- Reacts with the acidic molasses to lift the cookies and promote browning.
- Flour
- Provides the structure that holds the cookies together.
- Strong coffee
- Adds liquid to bind the dough and deepens the flavor.
The step that matters
Gradually add the flour. Flour absorbs liquid and develops gluten. Adding it slowly lets you stop once the dough is workable; too much flour makes the cookies dry and tough.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, coffee, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Clovefits about as well
Fit is the average pairing score against sugar, molasses, butter, coffee, flour. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
