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 ↓
Pinafore Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a mixing bowl, cream the butter until smooth.
Gradually add the sugar and mix until well combined.
Stir in the milk and baking soda.
Add the beaten eggs, corn starch, flour, and cream of tartar, then mix until the batter is smooth.
Bake
Pour the batter into baking sheets and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air, giving the cake a tender, rich texture.
- Sugar
- Sweetens the cake and helps it brown while creaming with the butter.
- Eggs
- Add structure and binding, helping the batter hold together as it bakes.
- Flour
- Forms the main structure of the cake once baked.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Acts as an acid that supports the baking soda's reaction and stabilises the batter.
The step that matters
Stirring in the baking soda with the milk. Baking soda needs an acid to react and release gas for rising. Adding it to the liquid and then mixing promptly lets the reaction work in the batter, so the cake rises well once it is in the oven.
