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).
In a bowl, beat the egg whites until stiff.
In another bowl, cream together the sugar and butter.
Add the milk to the sugar mixture and mix well.
Gradually add the flour and baking powder, mixing until smooth.
Divide the batter in half.
Flavor, layer and bake
Color one half with strawberry coloring and flavor it with vanilla.
Flavor the other half with lemon extract.
Pour the white batter into a baking pan, then add the pink batter on top.
Bake slowly 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
- Egg whites
- Beaten until stiff, they trap air that gives the cake lift and a light crumb.
- Butter
- Creamed with sugar, it adds fat that gives the cake a tender texture and rich flavor.
- Sugar
- Creamed with butter, it sweetens the cake and helps create a fine, tender crumb.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and become airy.
- Milk
- Adds moisture that hydrates the flour and keeps the batter loose and the cake soft.
The step that matters
Bake slowly until a toothpick comes out clean. A low oven bakes the cake evenly and gently, so the center sets without the edges drying out or browning too much. Testing with a toothpick shows when the center is set and no longer wet with batter.
