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
Preheat the oven to 350°F (175°C).
In a large bowl, mix the sugar, flour, milk, melted butter, and beaten eggs.
Add the cream of tartar and baking soda, and mix until smooth.
Pour the batter into a greased cake pan and bake for 30-35 minutes.
Make the custard
For the custard, heat the milk in a saucepan.
In a bowl, whisk the egg yolks and sugar together.
Slowly add the hot milk to the egg mixture, stirring constantly.
Return the mixture to the saucepan and cook over low heat until thickened.
Remove from heat and stir in the vanilla extract once cooled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness as they set the batter during baking.
- All-purpose flour
- Forms the main structure of the cake batter.
- Sugar
- Adds sweetness and helps the cake brown and keep moist.
- Butter
- Adds fat for tenderness and a rich flavor to the cake.
- Egg yolks
- Thicken the custard and add richness through their fat and emulsifying proteins.
- Cream of tartar
- Acidifies the batter and helps stabilize it along with the baking soda for rising.
The step that matters
Adding the hot milk to the egg yolks. Pouring hot milk in too quickly can scramble the yolks. Adding it slowly while stirring gently warms the yolks so the custard thickens smoothly.
