Why it works: Sugar and molasses 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, mix together the sugar, molasses, butter, and warm water until well combined.
Add the baking soda and ginger, then gradually incorporate flour until the dough is manageable.
Roll out the dough on a floured surface and cut into squares.
Bake and serve
Bake in a preheated oven at 350°F (175°C) until firm.
Allow to cool before serving.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Adds moisture, dark color, and a deep sweet flavor to the dough.
- Baking soda
- Reacts with the molasses acid to lighten the dough and help it spread and brown.
- Butter
- Adds fat for tenderness and flavor in the dough.
- Sugar
- Sweetens the dough and helps it brown as it bakes.
- Flour
- Provides structure so the dough can be rolled and cut.
The step that matters
Adding the flour gradually. Adding flour slowly lets you stop once the dough is manageable. Too much flour makes the gingerbread dense and dry, while too little leaves it sticky and hard to roll.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Gingerthe original
Fit is the average pairing score against sugar, molasses, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
