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
Combine butter and boiling water in a saucepan; bring to a boil.
Stir in 1 ½ cups of flour while boiling until well combined.
Let the mixture cool.
Add 5 beaten eggs and mix well.
Bake the puffs
Drop spoonfuls of the mixture onto baking sheets.
Bake for 30 minutes at 400°F (200°C).
Make and fill the custard
Boil 1 pint of milk for the filling.
In a bowl, mix 1 cup of sugar, ⅔ cup of flour, and 2 beaten eggs.
Stir the egg mixture into the boiling milk until thickened.
Once partially cool, add lemon flavoring to the filling.
Fill the baked puffs with the lemon‑flavored filling.

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
- Forms the starch structure that holds the puffs' shape as they set.
- Butter
- Adds fat and richness, and softens the dough texture.
- Eggs
- Provide structure and lift, setting the baked puffs and thickening the filling.
- Milk
- Forms the liquid base of the filling, adding richness and body.
- Sugar
- Sweetens the filling and balances the flavor.
The step that matters
Stir the egg mixture into the boiling milk until thickened. Eggs can scramble if they hit very hot liquid too quickly. Adding them gradually while stirring keeps the custard smooth, and the starch in the flour helps it thicken.
Swap the lemon

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.
