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
Preheat your oven to 350°F (175°C).
Make the dough
In a bowl, cream together the sugar, molasses, and butter until smooth.
Stir in the strong coffee, ginger, baking soda, and salt.
Gradually add flour until the dough is firm enough to roll out.
Shape and bake
Roll out the dough on a floured surface and cut into desired shapes.
Place on a baking sheet and bake for 10-12 minutes or until lightly browned.

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 dough brown during baking.
- Molasses
- Adds moisture, deep sweetness and a dark color to the cookies.
- Butter
- Adds fat for tenderness and flavor, and creams with sugar to add structure.
- Baking soda
- Reacts with acidic molasses to produce gas that helps the cookies rise and spread.
- Strong coffee
- Adds liquid and a deep aroma that complements the molasses and ginger.
The step that matters
Gradually add flour until the dough is firm enough to roll out. Adding flour gradually lets you judge the dough's texture by feel. Too much flour makes cookies dry and tough, while too little leaves the dough sticky and hard to shape.
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.
