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 Ginger-bread
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.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a large bowl, mix the flour, sugar, butter, ginger, and baking soda.
Add the eggs and mix until well combined.
If desired, add seeds to the mixture.
In a separate bowl, combine molasses with milk or water to adjust thickness.
Stir in the dissolved baking soda, butter, ginger, and salt.
Combine both mixtures and add enough flour to roll out the dough.
Bake
Divide the dough into two cakes and bake 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
- Flour
- Forms the structure of the dough so it can be rolled out and hold its shape.
- Eggs
- Bind the mixture and add richness and structure to the crumb.
- Molasses
- Adds sweetness, dark color, and moisture, and gives gingerbread its characteristic flavor.
- Baking soda
- Reacts with the acidity in molasses to produce gas, helping the cake rise and lighten.
- Butter
- Adds fat for tenderness and flavor in the dough.
- Sugar
- Adds sweetness and helps browning and moisture in the baked cake.
The step that matters
Adding the dissolved baking soda. Baking soda must be fully dissolved before it is stirred in, so it spreads evenly through the dough. Unevenly distributed soda can leave bitter, soapy patches and uneven rising.
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.
