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 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
Beat the butter until creamy.
Gradually add the sugar and mix well.
Stir in the milk.
Beat the egg whites until stiff peaks form in a separate bowl.
Fold the egg whites into the butter mixture.
Sift together the flour, corn starch, cream of tartar, and baking soda.
Gently fold the dry ingredients into the wet mixture.
Bake
Pour the batter into baking sheets and bake for 20 minutes.

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 and give the cake a tender, rich crumb.
- Eggs
- Whipped whites add lift and structure, while the yolks add richness and help set the crumb.
- Flour
- Provides the main structure that sets as the cake bakes.
- Sugar
- Sweetens the cake and helps tenderize the crumb while creaming with the butter.
- Baking soda
- Reacts with the cream of tartar to produce gas that helps the batter rise.
- Cream of tartar
- Acidifies the batter, activating the baking soda and stabilizing the whipped egg whites.
The step that matters
Fold the egg whites into the butter mixture. Folding gently keeps the air in the whipped egg whites. Stirring or deflating the batter loses that trapped air, which reduces lift and leaves a denser cake.
