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 ↓
White Layer 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
In a large bowl, mix the egg whites until frothy.
Add corn starch, sugar, flour, butter, baking powder, milk, and vanilla, then mix until smooth and well combined.
Pour the batter into deep pie pans.
Bake and assemble
Bake until a toothpick inserted in the center comes out clean.
Once cooled, spread soft icing between each layer, adding a tablespoon of bright red jelly for color.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a froth, they trap air that helps the layers rise and set light.
- Flour
- Provides the main structure that holds the cake's crumb together as it bakes.
- Sugar
- Sweetens the cake and helps keep it moist and tender while browning.
- Baking powder
- Releases gas when heated, helping the batter rise in the oven.
- Butter
- Adds fat for richness and a tender texture.
- Milk
- Hydrates the flour and starch so the batter forms and bakes evenly.
The step that matters
Baking until a toothpick comes out clean. Starch and egg proteins set as the cake bakes. Pulling it out too early can leave a wet, sunken centre, while overbaking dries the crumb and makes it crumbly.
“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.
