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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dough
In a pan, combine the butter and milk over medium heat until boiling.
Add the flour and mix well until combined.
Allow the mixture to cool, then mix in the eggs and reserved egg whites along with sugar to taste.
Bake
Pour the mixture into a baking dish and bake in a moderate oven at 350°F (175°C) until puffed and golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds richness and tenderness by coating flour strands and limiting toughness.
- Milk
- Provides moisture and steam for lift, and its milk sugars help the surface brown.
- All-purpose flour
- Forms the starch and gluten structure that holds the puffs together as they bake.
- Eggs
- Add structure as they set and lift the batter as steam expands during baking.
The step that matters
Cool the mixture before adding the eggs. If the flour paste is still very hot, the eggs can partly scramble and fail to blend smoothly. A cooled, smooth base lets the eggs emulsify evenly, so the batter can expand and puff in the oven.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
