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 says “a hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Mix together the butter or beef drippings, molasses, brown sugar, ground ginger, and baking soda dissolved in cold water until thoroughly combined.
Add the flour, measuring it by dipping from the bag and sifting after measuring.
Shape and bake
Roll out the dough to an eighth of an inch thick and cut with a 2-inch cutter.
Lift the cookies with a broad knife or cake turner and arrange them on the inverted bottom of buttered tins.
Bake in a moderate oven at 350°F (175°C) until done, being careful not to burn.
Store
Store in air-tight glass jars in a dry place.

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 or beef drippings
- Provides fat that gives the cookies a tender, crisp texture.
- Molasses
- Adds moisture, dark color, and a rich, deep sweetness to the dough.
- Brown sugar
- Adds sweetness and moisture, and helps the cookies brown and stay soft.
- Ground ginger
- Supplies the warm, spicy aroma and flavor that defines the cookie.
- Baking soda
- Reacts with the molasses's acidity to lighten the dough and help the cookies spread and rise.
- All-purpose flour
- Provides the structure that holds the cookies together as they bake.
The step that matters
Bake until done without burning. Molasses and sugar brown quickly, so the cookies can go from done to scorched in a short time. Thin dough cooks fast, and the sugars caramelize and then burn once past that point, giving a bitter taste.
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.
