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 ↓

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, then add the eggs and mix well.
Stir in the sweet milk.
Gradually add the flour and baking powder, mixing until smooth.
Pour the batter into a greased pie dish and bake for 25-30 minutes.
Make the custard
For the custard, beat the eggs and mix with cornstarch dissolved in a little milk.
Heat the pint of milk and add the egg mixture, stirring constantly until it thickens.
Sweeten the custard to taste and let it cool.
Assemble and serve
Once the cake is baked and cooled, cut it and spread the custard between the 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 thicken the custard as they set with heat.
- Butter
- Adds richness and tenderness to the cake crumb.
- Flour
- Provides the structure that holds the cake together.
- Baking powder
- Releases gas that makes the cake rise and turn light.
- Cornstarch
- Thickens the custard into a smooth, spreadable filling.
- Sugar
- Sweetens the cake and custard and softens the crumb.
The step that matters
Stirring the custard until it thickens. Egg proteins set with heat, so the custard can curdle or turn lumpy if it boils or heats too fast. Constant stirring spreads the heat evenly and lets the cornstarch thicken the milk smoothly.
