Why it works: Cocoa and vanilla work together. They rank in the top 4% of all ingredient pairs, and cooks put them together in 357 recipes. Both carry sotolon, which smells curry, maple. The science ↓
White and Brown Ribbon 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
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the beaten egg whites and mix well.
Stir in the sweet milk.
Sift the flour with the baking powder several times, then add it to the mixture.
Flavor, layer and bake
Take one-third of the batter and mix in cocoa to achieve desired darkness.
Flavor the dark batter with vanilla and the light batter with lemon.
In two square pans, pour the light batter first, then top with the dark batter.
Bake until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten whites trap air and add structure and lift to the crumb.
- Butter
- Creamed with sugar, it adds richness and a tender texture.
- Sugar
- Creamed with butter, it sweetens and helps the crumb brown and stay soft.
- All-purpose flour
- Its proteins set during baking to give the cake its main structure.
- Baking powder
- Releases gas in the heat, making the cake rise and become light.
- Sweet milk
- Adds moisture and loosens the batter so it bakes evenly.
The step that matters
Bake until a toothpick comes out clean. The cake keeps setting after it leaves the oven. Pulling it too early can leave a wet center that sinks, while overbaking dries the crumb.
