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 ↓
Sour Milk 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. 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 the oven to 350°F (175°C).
Make the batter
In a bowl, cream the butter.
Add the molasses and mix well.
In another bowl, combine the flour, baking soda, and ground ginger.
Gradually add the dry ingredients to the wet mixture.
Stir in the sour milk and egg until well combined.
Pour the batter into a flat baking tin.
Bake
Bake for about 25-30 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 starch structure that sets the crumb of the gingerbread.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the batter.
- Sour milk
- Its acidity activates the baking soda and adds moisture and tenderness.
- Molasses
- Adds sweetness, dark colour and moisture, and contributes to the gingerbread flavour.
- Egg
- Binds the batter and helps give the cake its set structure.
- Butter
- Adds fat for richness and a tender texture.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding dry ingredients slowly helps them blend evenly without overmixing. Overmixing develops gluten and can make the gingerbread tough and dense, while even mixing keeps the leavening evenly distributed.
Swap the ginger
How well each one fits the dish's main ingredients (butter, flour, molasses, milk, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against butter, flour, molasses, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
