Why it works: Milk and butter 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 ↓

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 cake
Preheat the oven to 350°F (175°C).
Beat the egg yolks thoroughly, then add sugar, hot water, flour, and baking powder.
Fold in the beaten egg whites and any desired flavoring.
Pour the mixture into a jelly pan and bake until golden.
Make the filling
For the filling, boil the milk.
In a separate bowl, mix sugar, egg, and butter until well combined.
Dissolve cornstarch in a little milk and add to the mixture.
Cook the filling until thick, then flavor it and let it cool.
Assemble
Once cool, split the cake through the center.
Spread the filling between the split sections of the cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whites build the cake's structure and give it lift and richness.
- Flour
- Forms the cake's structure once its proteins set in the oven.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Cornstarch
- Thickens the filling as it cooks, giving it a smooth, spreadable body.
- Milk
- Forms the base of the filling, adding richness and body.
The step that matters
Cooking the filling until thick. Cornstarch only thickens fully once the mixture reaches a boil and is stirred while cooking. Stopping early leaves a runny filling that will not hold between the cake layers.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
