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 ↓
Ginger-snaps
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 the oven to 350°F (175°C).
Make the dough
In a bowl, combine molasses, brown sugar, and butter or lard.
Dissolve baking soda in a small amount of hot water and add to the mixture.
Mix until thick, then roll out the dough thinly.
Shape and bake
Cut into desired shapes and place on a baking sheet.
Bake for 10-12 minutes or until lightly browned.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 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
- Provides dark color, rich flavor, and moisture that keeps the cookies chewy.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown during baking.
- Butter or lard
- Adds fat for tenderness and richness, and carries the ginger flavor.
- Ground ginger
- Supplies the spicy, warm aroma that defines the cookie.
- Baking soda
- Reacts with the acidic molasses to lift the dough and help it spread and brown.
The step that matters
Dissolving the baking soda in hot water. Baking soda must be fully dissolved before mixing so it reacts evenly with the acidic molasses. Undissolved pockets can leave bitter spots or uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, butter):
- Cinnamonfits better
- Gingerthe original
- Nutmegfits about as well
- Clovefits about as well
Fit is the average pairing score against molasses, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
