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 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
Stir half of the baking soda into the molasses and the other half into the sour milk until foamy.
Combine all ingredients in a bowl and mix thoroughly.
Bake
Pour the batter into a greased baking pan.
Bake in a moderate oven at 350°F (175°C) 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
- Molasses
- Adds sweetness, dark color and a moist, tender crumb to the cake.
- Sour milk
- Its acidity reacts with the baking soda to produce gas that lifts the cake.
- Baking soda
- Reacts with the acidic sour milk and molasses to make the cake rise and stay light.
- Flour
- Provides the structure that sets the batter into a cake as it bakes.
- Butter or lard
- Adds fat that softens the crumb and adds richness.
The step that matters
Foaming the baking soda into the molasses and sour milk. Baking soda only leavens when it meets an acid, so it must be stirred into the acidic molasses and sour milk right away. Letting the mixture sit lets the gas escape and reduces the lift in the finished cake.
Swap the ginger
How well each one fits the dish's main ingredients (molasses, milk, butter, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against molasses, milk, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
