Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Silver and Gold 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batters
Preheat the oven to 350°F (175°C).
Beat the egg whites in a bowl until stiff peaks form.
Cream together the butter and sugar in another bowl until light and fluffy.
Add the milk or water, flour, baking powder, and flavoring to the butter mixture, mixing well.
Gently fold in the beaten egg whites.
Beat the egg yolks for the gold layer and mix with sugar, sifted flour, butter, water or milk, and flavoring.
Bake
Pour the silver batter into a greased cake pan, followed by the gold batter on top.
Bake for 30–40 minutes or 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
- Whipped to stiff peaks, they give the silver layer its lift and airy structure.
- Egg yolks
- They add richness, colour and tenderness to the gold layer.
- Flour
- Its proteins set during baking to give the cake its structure.
- Butter
- Creamed with sugar to trap air, it adds tenderness and flavour.
- Sugar
- Sweetens the cake and helps create a light, creamed texture with the butter.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Fold in the beaten egg whites gently. Stiff egg whites hold air that gives the silver layer its lift. Vigorous stirring knocks that air out, leaving a denser cake.
