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 ↓
Sour Milk Gingerbread
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Mix together baking soda, sour milk, and molasses.
In a separate bowl, combine all the dry ingredients and stir until well mixed.
Add the milk and molasses mixture, and beat vigorously for a few moments.
Bake and serve
Turn the batter into shallow pans.
Bake in a moderate oven at 350°F (175°C) for twenty-five to thirty minutes.
Serve hot.

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
- Molasses
- Adds sweetness, moisture, dark color and its deep, rich flavor to the gingerbread.
- Baking soda
- Reacts with the acid in the sour milk to release gas, which makes the gingerbread rise.
- Sour milk or cream
- Its acidity activates the baking soda and its liquid moistens and tenderizes the batter.
- Flour
- Provides the structure that holds the gingerbread together as it sets in the oven.
- Ginger
- Supplies the warm, spicy aroma that defines the flavor of gingerbread.
The step that matters
Beating the batter vigorously after combining the liquids. Once the acidic milk mixture meets the baking soda and flour, gas starts forming quickly, so the batter should be mixed and put into the pans promptly to keep the bubbles that give the gingerbread its lift.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, milk, flour, butter):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
