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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, beat the eggs and mix in the sugar and butter until well combined.
Stir in the molasses.
Gradually add the flour, allspice, baking soda, and cream of tartar dissolved in sweet milk, mixing well.
Bake
Pour the batter into a large pan and bake until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as they set in the oven.
- Flour
- Provides the main structure that holds the cake's crumb together.
- Butter
- Adds fat for tenderness and rich flavor.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda to help the cake rise.
The step that matters
Adding the baking soda and cream of tartar. Baking soda and cream of tartar react to produce gas that lifts the batter. Mixing them in evenly and then baking promptly keeps the rise consistent, so the cake does not turn out dense or unevenly textured.
Swap the allspice
How well each one fits the dish's main ingredients (flour, egg, sugar, butter, molasses, cream, milk):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Allspicethe original
Fit is the average pairing score against flour, egg, sugar, butter, molasses, cream, milk. Candidates are from the same food group and used in at least 100 recipes.
