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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the dough
In a bowl, cream together the butter, sugar, molasses, and cold coffee.
Add the baking soda and ginger, mixing well.
Gradually add flour until the dough is stiff enough to roll out thin.
Shape and bake
Roll out the dough and cut with a cookie cutter.
Place on a baking sheet and bake in the preheated oven until crisp.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Butter
- Adds fat and richness, helping the cookies stay tender and spread while baking.
- Molasses
- Adds sweetness, deep flavor, and moisture that contributes to the cookies' color.
- Baking soda
- Reacts with the acidic molasses to lift the dough and help the cookies spread.
- Flour
- Provides structure, so the dough can be rolled thin and hold its cut shapes.
The step that matters
Adding the flour gradually. Flour gives the dough its structure. Adding it slowly lets you stop once the dough is stiff enough to roll thin, so the cookies stay crisp rather than tough or cakey.
Swap the ginger
How well each one fits the dish's main ingredients (butter, sugar, molasses, coffee, flour):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Clovefits about as well
Fit is the average pairing score against butter, sugar, molasses, 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.
