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 ↓

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
Dissolve the baking soda in boiling water.
In a bowl, mix molasses, butter or lard, ginger, and the dissolved baking soda.
Add the egg and mix until very soft.
Shape and bake
Chill the dough if necessary, then roll out and cut into shapes.
Bake in a preheated oven at 350°F (175°C) until firm.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 dark colour, and its acidity activates the baking soda.
- Baking soda
- Reacts with the molasses acid to release gas, giving the cookies lift and a softer texture.
- Butter or lard
- Adds fat for tenderness and a rich mouthfeel in the baked cookies.
- Egg
- Binds the dough and helps give the baked cookies structure.
- Ginger
- Provides the warm, spicy aroma that defines the cookies.
The step that matters
Dissolve the baking soda fully in boiling water. Baking soda reacts with the acid in molasses to release carbon dioxide. If it is fully dissolved and mixed in evenly, the lift is uniform. Undissolved clumps can leave soapy, bitter, or crumbly spots.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, butter, egg):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
- Gingerthe original
Fit is the average pairing score against molasses, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
