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
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, combine sugar, milk, flour, butter, baking soda, and cream of tartar, then mix until smooth and well combined.
Add flavoring to taste.
Bake
Pour the batter into a greased baking pan.
Bake immediately for about 30-35 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
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Cream of tartar
- Acidifies the batter so the baking soda reacts and helps give a tender crumb.
- Sugar
- Sweetens the cake and helps keep it moist and browning evenly.
- Milk
- Hydrates the flour and adds moisture to the batter.
- Butter
- Adds fat for richness and a softer, more tender texture.
The step that matters
Bake immediately after mixing. Baking soda and cream of tartar start reacting as soon as they are wet. Leaving the batter to sit lets the gas escape before the cake sets, so it can rise poorly and turn flat or dense.
