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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a saucepan, bring the water and butter to a boil.
Stir in the flour quickly until it forms a ball that leaves the sides of the pan.
Let the mixture cool, then beat in the eggs one at a time, mixing well after each addition.
Allow the mixture to sit in a warm place for 30 minutes, stirring occasionally.
Bake the shells
Drop tablespoonfuls of the mixture onto a buttered baking sheet, spaced 2 inches apart.
Bake in a preheated oven at 400°F (200°C) for about 20 minutes until puffed and brown.
Make the cheese filling
For the filling, melt the cheese with the milk, baking soda, mustard, white pepper, cayenne, nutmeg, and browned flour in a saucepan over low heat.
Once melted, stir in the beaten eggs and bake in a buttered dish until nearly solidified.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Starch gelatinises with the water and egg to form the structure of the choux paste.
- Eggs
- Add moisture and structure, and their steam helps the paste puff while baking.
- Grated cheese
- Provides rich flavor and, with the eggs, sets into a firm filling.
- Milk
- Adds moisture and softness to the cheese filling.
The step that matters
Let the mixture cool before adding the eggs. Eggs added to very hot paste can scramble and the dough will not blend smoothly. Adding them one at a time to a cooled paste lets the dough emulsify, so it stays smooth and can puff properly in the oven.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, flour, egg, cheese, milk, mustard, pepper):
- Capersfits better
- Nutmegfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against butter, flour, egg, cheese, milk, mustard, pepper. Candidates are from the same food group and used in at least 100 recipes.
