Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. 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 the batter
Preheat the oven to 350°F (175°C).
In a mixing bowl, cream the butter and sugar together until light and fluffy.
Add the water and mix well.
Gradually add the sifted pastry flour and baking powder, mixing until combined.
Stir in the vanilla.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Bake
Divide the batter evenly between two greased cake pans.
Bake for about 20 minutes or until a toothpick inserted in the center comes out clean.

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
- Butter
- Creams with sugar to trap air and give the cake a tender, rich texture.
- Sugar
- Sweetens the cake and helps create a light, fluffy creamed base.
- Pastry flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy crumb to the batter.
The step that matters
Folding in the egg whites. Whipped whites hold air that gives the cake its lift. Stirring them in vigorously deflates the foam, leading to a dense, flat layer, so fold gently until just combined.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, sugar, flour, egg):
- Raisinfits better
- Vanillathe original
- Figfits less well
- Lemonfits less well
Fit is the average pairing score against butter, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
