Why it works: Strawberry and vanilla are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,385 recipes. Both carry p-vinylguaiacol, which smells spicy, fruity. The science ↓
Troy Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Preheat the oven to 300°F (150°C).
Cream the butter and sugar together until light and fluffy.
Add the egg whites and mix the batter well.
Sift the flour and baking powder together.
Gradually add the sifted flour mixture to the batter.
Stir in the milk until smooth.
Divide the batter in half.
Flavor and bake
Color one half with strawberry coloring and flavor it with vanilla.
Flavor the other half with lemon extract.
In a greased cake pan, pour in the white batter first, then the pink batter on top.
Bake in the preheated oven until a toothpick inserted comes out clean.

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, giving a light, tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps creaming hold air for a light texture.
- Egg whites
- Add structure and help the batter set as it bakes.
- Flour
- Forms the structure that holds the cake together as it sets.
- Milk
- Adds moisture and loosens the batter to a smooth consistency.
- Baking powder
- Releases gas when heated, helping the cake rise and turn light.
The step that matters
Bake until a toothpick comes out clean. Underbaking leaves wet batter in the center that can collapse as it cools, while overbaking dries the crumb. A clean toothpick shows the structure has set.
