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 ↓
Soft Ginger Cake
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
Beat the egg and mix in the ginger, molasses, and sour milk.
Combine the flour and baking soda in another bowl.
Gradually add the dry ingredients to the wet mixture, stirring until smooth.
Melt the butter and fold it into the batter.
Bake
Pour the batter into a greased baking pan and bake for about 30–35 minutes or 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
- Egg
- Binds the batter and adds structure as the cake sets in the oven.
- Baking soda
- Reacts with the acidic sour milk and molasses to release gas, so the cake rises and stays soft.
- Molasses
- Adds sweetness, dark color, and moisture to the cake.
- Sour milk
- Its acidity activates the baking soda and tenderizes the crumb.
- Flour
- Forms the gluten and starch structure that holds the cake together.
- Butter
- Adds fat for richness and a tender texture.
The step that matters
Adding the baking soda with the flour. Baking soda needs an acid to react and release gas. Mixing it evenly with the flour before combining, then stirring only until smooth, keeps the rise even and avoids overworking the gluten, which would make the cake tough.
Swap the ginger
How well each one fits the dish's main ingredients (egg, molasses, milk, flour, butter):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against egg, molasses, milk, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
