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
Make the dough
In a porcelain saucepan, combine molasses, brown sugar, butter, ginger, baking soda, and salt.
Heat the mixture over medium heat, stirring until it boils, then maintain a boil for 5 minutes.
Pour the mixture into a large bowl and quickly stir in enough flour to form a stiff dough.
Mold the dough with your hands as it becomes too stiff for a spoon.
Shape and bake
Roll out the dough very thin on a floured surface and cut into small rounds.
Place the rounds in shallow pans and bake immediately.

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
- Provides the dark color, rich flavor, and moisture that keeps the snaps chewy-crisp.
- Butter
- Adds fat for tenderness and flavor, and helps the dough hold together.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown as they bake.
- Baking soda
- Reacts with the acidic molasses to lighten the dough and help it spread and crisp.
- Flour
- Provides the structure that turns the mixture into a stiff, shapeable dough.
The step that matters
Maintain a boil for 5 minutes. Boiling the molasses mixture cooks off water and changes its sugar concentration, so the dough firms up and bakes crisp rather than soft. Stirring in the flour quickly keeps the hot mixture from stiffening unevenly.
Swap the ginger
How well each one fits the dish's main ingredients (butter, molasses, sugar, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against butter, molasses, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
