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 ↓
Alum Gingerbread
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.
Prepare the leavening
In half of the boiling water, dissolve the alum.
In the other half, dissolve the baking soda.
Make the dough
Combine the molasses, melted lard, ginger, and salt in a bowl.
Stir in the water mixtures.
Add enough flour to form a kneadable dough.
Shape and bake
Roll the dough to about ½ inch thick.
Cut into oblong shapes and bake in a 400°F (200°C) oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides sweetness, dark color, and moisture for a soft, rich crumb.
- Lard
- Adds fat that tenderizes the dough and carries the spice flavor.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the gingerbread rise.
- Alum
- Acts as an additional acid that reacts with the baking soda to aid leavening and set the texture.
- Flour
- Provides the structure that holds the dough together and sets as it bakes.
The step that matters
Dissolving the baking soda and alum in water. Baking soda must react with acid to release carbon dioxide for rising. Dissolving both fully before mixing ensures they distribute evenly through the dough, so the gingerbread rises uniformly instead of in pockets or unevenly.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, flour):
- Jalapenofits better
- Cinnamonfits better
- Allspicefits about as well
- Gingerthe original
Fit is the average pairing score against molasses, flour. Candidates are from the same food group and used in at least 100 recipes.
