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, mix the egg, molasses, sugar, melted butter, and milk.
Add the flour, baking soda, cream of tartar, spices, and vinegar. Mix until smooth.
Pour the batter into a round pan or gem pans.
Bake
Bake for 20 minutes or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Provides the main structure that sets as the cake bakes.
- Egg
- Binds the batter and adds structure and richness to the crumb.
- Molasses
- Adds moisture, dark color, and a deep sweetness to the cake.
- Baking soda
- Reacts with the acidic vinegar and cream of tartar to produce gas that lifts the batter.
- Butter
- Adds fat for tenderness, moisture, and rich flavor.
- Milk
- Adds moisture and helps hydrate the flour to form the batter.
The step that matters
Mixing in the baking soda and acids. Baking soda needs the acids from vinegar and cream of tartar to release gas for rising. Once the batter is mixed and in the pan, it should go into the oven promptly, because the leavening reaction begins right away and loses strength while the batter waits.
Swap the clove
How well each one fits the dish's main ingredients (egg, molasses, sugar, butter, milk, flour, cream):
- Cinnamonfits better
- Nutmegfits better
- Gingerfits about as well
- Clovethe original
Fit is the average pairing score against egg, molasses, sugar, butter, milk, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
