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 ↓

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 your oven to 350°F (175°C).
In a mixing bowl, cream the butter and sugar together until light and fluffy.
Add the egg and sweet milk, mixing well.
In a separate bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Bake
Pour the batter into a greased cake pan.
Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cupcake together as it bakes.
- Butter
- Creaming with sugar traps air and adds tenderness and richness to the crumb.
- Sugar
- Sweetens the batter and helps it brown while creaming aerates it.
- Egg
- Binds the batter and adds structure and moisture as it sets in the oven.
- Baking soda
- Reacts with the acidic cream of tartar to release gas that makes the cupcake rise.
- Cream of tartar
- Acidifies the batter so it reacts with baking soda, adding lift and a softer crumb.
The step that matters
Stirring the dry ingredients into the wet mixture. Once flour meets liquid, gluten begins to form, so stirring only until just combined keeps the cupcakes tender rather than tough and dense.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
