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 ↓
Cream Pie
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Boil the milk in a saucepan.
In a bowl, mix corn starch with a little milk until smooth. Add the eggs to the corn starch mixture.
Once the milk has boiled, slowly stir in the corn starch mixture, sugar, butter, and lemon juice.
Make and bake the cake
For the cake, beat together the eggs and sugar until fluffy. Mix in the flour and baking powder, then add cold water.
Pour the batter into two pie pans and bake at 400°F (200°C) until golden.
Assemble
Split the cake while hot and spread the cream filling inside.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Add structure and richness to the custard and the cake batter.
- Corn starch
- Thickens the milk mixture into a smooth, sliceable cream filling.
- Butter
- Adds fat for a rich, smooth texture in the filling.
- All-purpose flour
- Provides the structure that holds the cake batter together when baked.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Sugar
- Sweetens the filling and cake and helps the cake brown.
The step that matters
Slowly stir the corn starch mixture into the boiling milk. Corn starch thickens only when heated, and adding it slowly while stirring keeps it dispersed so the filling does not turn lumpy.
