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 ↓
Custard or Cream Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake batter
Cream together the sugar and butter.
Dissolve the baking soda in the sweet milk and add it to the mixture.
Beat the egg whites to stiff peaks and fold them into the mixture.
Stir the cream of tartar into the sifted flour and quickly add it to the batter.
Bake the cake
Bake in a 350°F (175°C) oven in layers like a jelly cake.
Make the custard
For the custard, heat 2 cups of sweet milk in a dish set in boiling water.
When the milk boils, stir in the cornstarch or flour mixed with ½ cup sugar.
Add the egg yolks and a little cold milk, stirring into the boiling milk.
Cook until thickened, then set aside to cool and add flavoring.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs whites
- Whipped to stiff peaks, they trap air and give the cake its light, airy structure.
- Butter
- Creamed with sugar, it adds richness and tenderness to the crumb.
- Sugar
- Sweetens the cake and helps the creamed butter hold air for a softer texture.
- Sifted flour
- Provides the main structure that sets as the cake bakes.
- Cream of tartar
- Acidifies the batter and stabilizes the whipped egg whites so they hold their peaks.
- Cornstarch or flour
- Thickens the custard as it heats, giving it a smooth, sliceable body.
The step that matters
Folding in the beaten egg whites. Stiff whites hold the cake's rise, so they must be folded gently to keep air in. Overmixing deflates them and yields a dense cake.
