Why it works: Milk and butter 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 ↓

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 batter
In a saucepan, boil the molasses and butter together.
Pour the boiling mixture over the flour in a large bowl.
Add the sour milk and ginger to the flour mixture.
Stir in the baking soda last and mix thoroughly.
Bake
Pour the batter into a greased baking pan and bake at 350°F (175°C) until a toothpick comes out clean.

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 sets the crumb as the batter bakes.
- Molasses
- Adds sweetness, moisture and the dark, rich colour and flavour typical of gingerbread.
- Sour milk
- Its acidity reacts with the baking soda, helping the cake rise and keeping it tender.
- Butter
- Adds fat that softens the crumb and gives a richer, moister texture.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the batter.
The step that matters
Stir in the baking soda last and mix thoroughly. Baking soda starts reacting as soon as it meets acid, so it should be added at the end and mixed evenly. Uneven mixing leaves pockets that over-rise or taste bitter, and waiting leaves the batter with less lift.
Swap the ginger
How well each one fits the dish's main ingredients (flour, molasses, milk, butter):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against flour, molasses, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
