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 ↓

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 the dough
Preheat your oven to 350°F (175°C).
In a bowl, mix molasses, sugar, and the butter‑lard mixture.
Add the egg and boiling water, then stir in the dissolved baking soda and ginger.
Gradually add flour until the dough is soft but manageable.
Shape and bake
Roll out the dough and cut into desired shapes.
Place on a baking sheet and bake for 10‑12 minutes.

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 dark color, moisture, and a rich, slightly bitter sweetness that defines the cookie.
- Butter and lard
- Provides fat that tenderizes the dough and gives a crisp, short texture.
- Baking soda
- Reacts with the acidic molasses to lift the dough and help the cookies spread and brown.
- Sugar
- Sweetens the dough and helps the cookies brown and crisp as they bake.
- Flour
- Provides the structure that holds the shaped cookies together.
- Ginger
- Supplies the warm, spicy aroma that characterizes the cookie.
The step that matters
Bake for 10‑12 minutes. Baking soda reacts quickly with molasses, and sugar darkens fast, so the cookies can go from chewy to burnt in minutes. Checking early keeps them crisp and evenly browned.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, sugar, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
