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 ↓
Cup-cake, Without Eggs
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 the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the cream and sour milk, then mix in the baking soda.
Gradually add the flour and grated nutmeg, mixing until well combined.
If the milk is not sufficiently sour, add the cream of tartar.
Bake
Pour the batter into a greased cake pan and bake for about 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the cake and, creamed with butter, helps give it a light, tender crumb.
- Butter
- Adds fat for richness and tenderness, and traps air when creamed with sugar.
- Sour milk
- Its acidity reacts with the baking soda to produce gas, helping the cake rise.
- Baking soda
- Reacts with the acid in the sour milk to release carbon dioxide, leavening the batter.
- Flour
- Provides the structure that sets as the cake bakes.
- Cream of tartar
- Adds acidity to help the baking soda react if the milk is not sour enough.
The step that matters
Adding the cream of tartar only if needed. Baking soda needs an acid to react and produce rising gas. If the sour milk is not acidic enough, the cake may rise poorly, so the acid must be checked and added as needed before the batter goes into the pan.
Swap the nutmeg
How well each one fits the dish's main ingredients (sugar, butter, cream, milk, flour):
- Cinnamonfits about as well
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against sugar, butter, cream, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
