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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Heat the molasses until scalding.
Stir in the baking soda while it foams.
Add the sugar, egg, ginger, and vinegar, mixing well.
Gradually add flour until the dough is light enough to roll.
Shape and bake
Roll out the dough thinly and cut into shapes.
Bake in a preheated oven at 400°F (200°C) until crisp.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides sweetness, moisture, and the dark color and rich flavor typical of ginger snaps.
- Baking soda
- Reacts with the acidic molasses and vinegar to produce gas that lightens the dough.
- Sugar
- Adds sweetness and helps the cookies brown and crisp as they bake.
- Egg
- Binds the dough and adds structure as it sets in the oven.
- Flour
- Provides the structure that lets the dough be rolled and hold its cut shapes.
The step that matters
Stir in the baking soda while the molasses foams. Baking soda reacts with the acid in the molasses and vinegar, so it must be added while the mixture is still foaming and reacting. Adding it late or in the wrong proportion can leave a bitter or soapy taste or uneven rising.

- Gingerthe original
Fit is the average pairing score against molasses, sugar, egg, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
