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 ↓
Cream Cakes
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux paste
Boil the water and butter together.
Stir in the flour while boiling.
Remove the mixture from heat to cool.
Once cool, add the eggs one at a time, stirring thoroughly without beating.
Add 1 teaspoon of cold water.
Drop spoonfuls of the mixture into a pan, as they do not rise much.
Bake
Bake for 15 to 20 minutes at 400°F (200°C) without opening the oven door.
Make the filling and fill the cakes
For the filling, boil the milk.
Beat the eggs, sugar, and flour together.
Stir the beaten mixture into the boiling milk until thickened.
Add essence of lemon to flavor.
When cool, fill the cakes.

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
- Bind the paste and give the cakes structure as they set in the oven.
- Butter
- Adds richness and fat to the paste, giving a tender texture.
- Flour
- Forms the starch base of the paste and thickens the filling.
- Milk
- Forms the liquid base of the filling, giving it a creamy body.
- Sugar
- Sweetens the filling and contributes to its thickened texture.
The step that matters
Stir the beaten mixture into the boiling milk until thickened. Adding the egg and flour mixture to boiling milk while stirring keeps the eggs from scrambling and lets the starch thicken the custard evenly.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, egg, sugar, milk):

- Lemonthe original
Fit is the average pairing score against butter, flour, egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
