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 ↓

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
Dissolve the baking soda in the hot water and add it to the molasses.
In a bowl, combine the melted lard and brown sugar.
Stir in the molasses and ginger.
Add enough flour to form a dough that can be rolled out.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in a preheated oven at 400°F (200°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Adds sweetness, depth of flavor and moisture to the dough.
- Baking soda
- Reacts with the acidic molasses to lighten the cakes as they bake.
- Lard
- Adds fat for tenderness and a short, rich texture.
- Flour
- Provides structure, letting the dough be rolled out and hold its shape.
- Ground ginger
- Provides the main spiced aroma and flavor.
The step that matters
Dissolving the baking soda in the hot water. Baking soda needs to be fully dissolved and mixed through the molasses so it reacts evenly. Pockets of undissolved soda can leave bitter spots and uneven rising.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, sugar, flour):
- Cinnamonfits better
- Jalapenofits better
- Gingerthe original
- Nutmegfits about as well
Fit is the average pairing score against molasses, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
