Why it works: Molasses and ginger are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 4,116 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Crisp Ginger Snaps
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
Heat molasses, lard, salt, and vinegar together in a pot.
Remove from heat and stir in baking soda and ginger.
Let the mixture cool.
Gradually mix in enough flour to form a stiff dough.
Shape and bake
Roll out the dough and cut into shapes.
Bake in a hot 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
- Adds sweetness, moisture, and a deep color to the cookies.
- Lard
- Provides fat for tenderness and a crisp texture.
- Baking soda
- Reacts with the acidic vinegar and molasses to lighten the dough.
- Flour
- Forms the structure that holds the stiff dough together.
- Vinegar
- Adds acidity that activates the baking soda.
The step that matters
Let the mixture cool before adding flour. Baking soda reacts with the acid in vinegar and molasses as soon as it is stirred in. Adding flour to a hot mixture can cause the reaction to fizz out early, and gradual, cooled mixing helps the dough form evenly and stiff enough to cut.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, vinegar, flour):
- Jalapenofits better
- Cinnamonfits better
- Allspicefits better
- Gingerthe original
Fit is the average pairing score against molasses, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
