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 a stiff froth and fold them into the mixture.
Stir the cream of tartar into the sifted flour and quickly add it to the batter.
Make the custard
For the custard, heat 2 cups of sweet milk in a double boiler until boiling.
Mix the cornstarch or flour with ½ cup sugar and the yolks of 4 eggs in a little cold milk.
Stir this mixture into the boiling milk and cook until thickened.
Set aside to cool, then add vanilla or lemon for flavor.
Bake
Bake in a 350°F (175°C) oven in layers like jelly cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten to a stiff froth, they trap air that lifts the cake.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- An acid that stabilizes the whipped egg whites and works with the baking soda to aid rising.
- Butter
- Creamed with sugar, it adds fat and tenderness to the cake crumb.
- Sifted flour
- Provides the structure that sets the cake as it bakes.
- Egg yolks
- Thicken the custard as they cook and add richness.
The step that matters
Cooking the custard until thickened. Egg yolks and starch thicken only when heated enough, but overheating can curdle the yolks. Cook gently in the double boiler, stirring, until the custard coats a spoon.
