Why it works: Butter and milk 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 ↓
Custard Cream 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 large bowl, mix sugar, melted butter, milk (or water), cream of tartar, baking soda, and flour until smooth. Add eggs and mix well.
Pour the batter into jelly cake pans and bake until golden.
Make the custard
For the custard, heat ½ pint of milk to boiling.
Stir in 2 teaspoons of cornstarch mixed with a little cold milk.
Take out a small amount of the mixture and gradually mix it with beaten eggs and sugar.
Return the egg mixture to the pot, stirring constantly until thickened.
Assemble
Once cool, flavor the custard and spread it between the cooled cake layers.

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, with cornstarch, thicken the custard.
- Flour
- Provides the structure that holds the cake layers together.
- Cream of tartar and baking soda
- React together to lighten the batter so the cake rises.
- Cornstarch
- Thickens the custard so it holds its shape between the layers.
- Butter
- Adds fat for tenderness and flavor in the cake.
The step that matters
Returning the egg mixture to the pot. Eggs can scramble if they meet hot milk too quickly. Tempering with a little hot mixture first, then stirring constantly over heat, lets the custard thicken smoothly as the egg proteins set gently.
