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 Puffs
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 paste
Bring 1 cup of hot water and ½ cup of butter to a boil in a saucepan.
Stir in 1 cup of sifted flour until a smooth paste forms.
Remove from heat and let cool slightly.
Stir in 3 eggs until well combined.
Bake the puffs
Drop tablespoonfuls of the mixture onto buttered baking sheets, ensuring they don't touch.
Bake in a preheated oven at 400°F (200°C) for 25-30 minutes without opening the oven door frequently.
Make and fill
Combine 1 cup of sweet milk, ½ cup of sugar, and 2 tablespoons of flour in a saucepan for the filling.
Cook over medium heat until thickened.
Add flavoring to taste.
Carefully slit the puffs.
Fill them with the cream.

Butter and flour 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
- Eggs
- Add structure and richness, setting the puffs as they bake.
- Butter
- Adds fat and richness, and helps the dough make a tender, flaky crumb.
- All-purpose flour
- Forms the starch paste that gives the puffs their structure.
- Sweet milk
- Provides moisture and body to the cream filling.
The step that matters
Avoid opening the oven door during baking. Opening the door early lets steam escape and cools the oven, so the puffs can collapse instead of rising and drying into hollow shells.
