Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. 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
Mix the flour, sugar, butter, ground ginger, and eggs in a large bowl.
Add the baking soda and seeds if desired.
Combine molasses with milk or water in another bowl to achieve desired thickness.
Stir in the dissolved baking soda, melted butter, ground ginger, and salt.
Combine both mixtures and add enough flour to form a dough.
Bake
Divide the dough into two cakes and roll out.
Bake in a preheated oven at 350°F (175°C) for about 20 minutes.

Flour and butter 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
- All-purpose flour
- Provides the main structure that holds the dough together as it bakes.
- Eggs
- Bind the dough and add structure and richness.
- Butter
- Adds fat for tenderness and flavor in the dough.
- Molasses
- Adds moisture, dark color, and a deep sweetness.
- Sugar
- Adds sweetness and helps the dough brown as it bakes.
- Baking soda
- Reacts with the molasses to help the dough rise and darken.
The step that matters
Adding enough flour to form the dough. The amount of flour sets how stiff the dough becomes. Too little leaves it sticky and hard to roll, while the dough must be firm enough to hold its shape once rolled out.
Swap the ginger
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, molasses, milk):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against flour, sugar, butter, egg, molasses, milk. Candidates are from the same food group and used in at least 100 recipes.
