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.
Make the dough
In a large bowl, combine molasses, sugar, shortening, ginger, baking soda, vinegar, and egg. Mix until well combined.
Gradually add flour until the dough is firm enough to roll out.
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 golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds deep sweetness, dark color, and moisture that keeps the snaps chewy.
- Sugar
- Sweetens the dough and helps the cookies brown and crisp as they bake.
- Shortening
- Provides fat that tenderizes the dough and gives a short, crisp bite.
- Baking soda
- Reacts with the acidic molasses and vinegar to lift the dough and promote spreading and browning.
- Vinegar
- Acidifies the dough so it reacts with baking soda, helping the snaps rise and stay light.
- Flour
- Provides the structure that lets the dough be rolled out and hold cut shapes.
The step that matters
Adding the flour. Flour should be added gradually until the dough is firm enough to roll out. Too little leaves the dough sticky and hard to cut, while too much makes the snaps dry and tough. Stop when the dough holds its shape.
