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 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 dough
Boil the butter and cold water together.
Gradually stir in the flour while boiling.
Let the mixture cool, then add the eggs, baking soda, and salt.
Drop spoonfuls of the mixture onto baking sheets.
Bake in a 400°F (200°C) oven until golden.
Make the filling
In a separate pot, boil the milk.
Beat together the sugar, flour, and eggs, then stir into the boiling milk.
Flavor with lemon or vanilla.
Assemble and serve
Cut a slit in the side of each cake and fill with the milk mixture after cooling.

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
- Flour
- Gelatinizes with the butter, water and eggs to give the cakes their structure.
- Eggs
- Set the dough and add richness and lift to the puffs.
- Butter
- Adds fat and richness to the dough and helps it puff when baked.
- Milk
- Forms the base of the filling, giving it a creamy, moist texture.
- Sugar
- Adds sweetness to the filling and helps it thicken with the flour and eggs.
The step that matters
Let the mixture cool before adding the eggs. If the dough is still hot, the eggs will scramble instead of blending smoothly, and the dough will be too loose to hold its shape and puff properly.
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.
