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 ↓
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.
Make the dough
In a large bowl, mix together the sugar, molasses, and lard until well combined.
Add the boiling water, baking soda, salt, and ground ginger, and stir until smooth.
Gradually add flour until the dough is easy to roll out but not too stiff.
Shape and bake
Roll out the dough on a floured surface and cut into desired shapes.
Bake in a preheated oven at 350°F (175°C) until crisp.

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 the deep sweet flavor typical of ginger snaps.
- Baking soda
- Reacts with the molasses acidity and helps the cookies spread and lighten as they bake.
- Lard
- Provides fat that tenderizes the dough and helps the cookies turn crisp.
- Flour
- Provides the structure that holds the dough together and sets as the cookies bake.
- Ground ginger
- Supplies the warm, spicy aroma that defines the cookie.
The step that matters
Adding the flour. Flour should be added gradually until the dough is easy to roll out but not too stiff. Too much flour makes the dough tough and dry, so the cookies bake up hard rather than crisp, while too little leaves it sticky and hard to shape.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, flour):
- Cinnamonfits better
- Jalapenofits better
- Gingerthe original
- Nutmegfits about as well
Fit is the average pairing score against sugar, molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
