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 ↓
Hard Gingerbread
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
In a bowl, combine molasses, sugar, and butter.
Dissolve baking soda in hot water and add to the mixture.
Gradually add flour until the dough is firm enough to roll.
Shape and bake
Roll out the dough and cut into desired shapes.
Bake in a moderate 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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Molasses
- Provides dark color, rich flavor, and moisture that keeps the gingerbread tender.
- Baking soda
- Reacts with the acidic molasses and hot water to produce gas that lightens the dough.
- Butter
- Adds fat for richness and a tender texture.
- Flour
- Provides the structure that lets the dough hold its firmness for rolling and cutting.
- Sugar
- Adds sweetness and helps with browning in the oven.
The step that matters
Adding the baking soda. Baking soda must be fully dissolved in the hot water before it is added, so it reacts evenly with the acidic molasses. Uneven distribution leaves pockets that may taste bitter or rise unevenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
