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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux pastry
Boil the butter and water together in a saucepan.
Gradually stir in the flour while boiling until combined.
Let the mixture cool.
Add the eggs one at a time, mixing well.
Drop spoonfuls of the mixture onto a baking tin.
Bake in a preheated oven at 400°F (200°C) until golden.
Make the cream
Beat together the milk, flour, sugar, and eggs for the cream.
Stir the mixture gradually into a boiling pot until thickened.
Flavor the cream with lemon.
Let the cream cool before filling the cakes.

Flour and butter 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
- All-purpose flour
- Provides the structure that holds the pastry and cream together as it sets.
- Butter
- Adds richness and tenderness to the pastry dough.
- Eggs
- Bind the mixture and help the pastry puff and set when baked.
- Milk
- Gives the cream its liquid base and smooth, rich body.
- Sugar
- Sweetens the cream and contributes to browning of the cakes.
The step that matters
Add the eggs one at a time, mixing well. Each egg must fully blend before the next is added so the dough becomes smooth and glossy. Adding eggs too fast can leave the dough broken, which stops it from rising properly in the oven.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter, egg, milk, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against flour, butter, egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
