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 ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat oven to 350°F (175°C).
Make the batter
In a bowl, mix together the sugar, molasses, butter, and sour milk.
In another bowl, combine the flour, baking soda, and ginger.
Gradually add the dry ingredients to the wet mixture.
Stir in the beaten egg until well combined.
Pour the batter into a greased baking pan.
Bake
Bake for about 30‑35 minutes or until a toothpick comes out clean.

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
- Flour
- Provides the structure that sets the batter as it bakes.
- Egg
- Binds the batter and adds structure and richness.
- Baking soda
- Reacts with the acidic sour milk and molasses to lift the batter.
- Molasses
- Adds sweetness, moisture, and the dark color and flavor of the gingerbread.
- Sour milk
- Adds acidity that activates the baking soda and tenderizes the crumb.
- Butter
- Adds fat that makes the crumb tender and rich.
The step that matters
Gradually add the dry ingredients to the wet mixture. Flour that is stirred too vigorously develops gluten, which makes the cake tough and dense. Mix only until the batter is just combined so the crumb stays tender.
Swap the ginger
How well each one fits the dish's main ingredients (sugar, molasses, butter, milk, flour, egg):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against sugar, molasses, butter, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
