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.
Make the dough
Preheat your oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour milk and molasses until combined.
In a separate bowl, whisk together the flour, ginger, and baking soda.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Shape and bake
Roll out the dough on a floured surface to your desired thickness.
Cut into shapes and place on a baking sheet.
Bake for 10-12 minutes or until lightly golden.

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 holds the cake together as it sets.
- Eggs
- Add structure and richness, and help bind the batter as they set in the oven.
- Unsalted butter
- Adds tenderness and richness, and carries flavor through the batter.
- Granulated sugar
- Creamed with the butter to trap air, and adds sweetness and gentle browning.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that helps the dough rise.
- Molasses
- Adds moisture, deep sweetness, and the dark color and warm flavor typical of ginger cake.
The step that matters
Gradually add the dry ingredients, mixing until just combined. Once flour meets liquid, gluten begins to form. Mixing only until combined keeps the texture tender, while overmixing makes the cake tough and dense.
Swap the ginger
How well each one fits the dish's main ingredients (flour, egg, sugar, butter, milk, molasses):
- Cinnamonfits better
- Nutmegfits better
- Gingerthe original
- Allspicefits about as well
Fit is the average pairing score against flour, egg, sugar, butter, milk, molasses. Candidates are from the same food group and used in at least 100 recipes.
