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 ↓
Chocolate 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).
Cream together the sugar and butter.
Add the milk and mix well.
In a separate bowl, combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
Beat the egg whites until stiff.
Fold the stiff egg whites into the batter.
Divide the batter in half.
Add the grated chocolate to one half.
Pour the chocolate batter into a greased cake pan.
Bake for 25-30 minutes.
Make the custard and assemble
Combine the yolks, sugar, chocolate, and sweet milk in a saucepan.
Cook over hot water, stirring until thickened.
Spread the custard between the layers of cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Whites are beaten to add lift and airiness; yolks enrich the custard and help it set.
- Baking powder
- Releases gas in the batter, causing the cake to rise and become light.
- Butter
- Adds fat for tenderness and flavor in the cake batter.
- Sugar
- Sweetens the cake and helps brown it while tenderizing the crumb.
- Grated chocolate
- Adds chocolate flavor to one batter half and to the custard.
The step that matters
Cook the custard over hot water, stirring until thickened. Egg yolks thicken as their proteins set with heat, but overheating can curdle them. Gentle heat and constant stirring keep the custard smooth.
