Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
A Good Cheap 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and sugar.
Add the egg and egg yolk, then mix in the sweet milk.
Sift together the flour and baking powder, then gradually add to the mixture.
Divide the batter into layers.
Bake and make the filling
Bake the layers until golden.
For the filling, pare the sour apples.
Grate the pared apples.
In another bowl, beat the egg white and granulated sugar until frothy.
Fold in the grated apple and vanilla extract.
Assemble the cake
Spread the apple cream between the layers.
Spread the apple cream on top of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add richness and structure as they set.
- Butter
- Adds fat and tenderness to the crumb when creamed with sugar.
- Flour
- Provides the structure that holds the layers together as they bake.
- Baking powder
- Releases gas during baking so the layers rise and stay light.
- Sugar
- Sweetens the cake and helps the layers brown as they bake.
- Sour apples
- Add acidity and moisture to the apple cream filling.
The step that matters
Fold in the grated apple and vanilla. Folding gently keeps the whipped egg white mixture airy. Overmixing deflates it, leaving the apple cream dense and heavy between the layers.
