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 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.
Make the cake batter
Preheat the oven to 350°F (175°C).
In a bowl, cream together the sugar and melted butter.
Add the beaten egg yolks and mix well.
In another bowl, combine the flour, baking soda, and cream of tartar.
Gradually add the dry ingredients to the wet mixture, alternating with the milk.
In a separate bowl, beat the egg whites until stiff peaks form, then fold them into the batter.
Bake and make the custard
Pour the batter into a greased cake pan and bake for 25-30 minutes.
For the custard, heat ½ pint of milk in a saucepan.
In a bowl, whisk together 2 eggs and sugar to taste, then add to the warm milk.
Flavor with vanilla and cook until thickened, stirring constantly.
Assemble
Once the cake is cooled, slice it and layer the custard between the slices.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trapped as stiff peaks lighten the batter and help the cake rise and set.
- Flour
- Forms the structure of the cake once its proteins set in the oven.
- Butter
- Adds richness, tenderness and flavor to the cake crumb.
- Baking soda
- Reacts with the acid in the batter to produce gas that helps the cake rise.
- Cream of tartar
- Acidifies the batter, stabilizing the whipped whites and aiding the rise with baking soda.
- Milk
- Moistens the batter and, in the custard, thickens into a creamy base as it heats.
The step that matters
Cooking the custard until thickened. Egg proteins thicken the milk only up to a point; overheating or stopping early can curdle the eggs or leave the custard runny. Stirring constantly spreads heat evenly and prevents scorching on the pan base.
