Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Pearl 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.
Make the batter
Cream together the sugar and butter until light and fluffy.
Add the milk and corn starch alternately, mixing well.
Sift the baking powder with the flour and gradually add to the mixture.
Fold in the beaten egg whites gently, then flavor with vanilla extract.
Bake
Bake in two layer cake pans at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that holds the cake's crumb together as it bakes.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Egg whites
- Trap air when beaten, giving the cake lightness and structure as they set.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Corn starch
- Softens the flour's gluten, producing a finer, more tender crumb.
- Sugar
- Creams with the butter to trap air and adds sweetness and browning.
The step that matters
Fold in the beaten egg whites gently. Vigorous stirring knocks out the air whipped into the egg whites, which leads to a dense, flat cake instead of a light one.
