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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux dough
Melt the butter in hot water.
While boiling, beat in the flour.
Remove from heat and let cool slightly.
Stir in the eggs one at a time without beating.
Bake the puffs
Drop spoonfuls onto baking sheets, about 2 inches apart.
Bake for about 25 minutes at 350°F (175°C).
Make and fill the cream
For the cream, boil the milk with 1 egg, sugar, and flour. Flavor with lemon.
When the puffs are done, open the side with a sharp knife and fill with the cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the water to add richness and tenderness to the dough.
- All-purpose flour
- Its starch gelatinizes with the boiling liquid and sets the dough's structure.
- Eggs
- Add moisture and structure, and their proteins help the puffs rise and set.
- Sugar
- Adds sweetness to the cream filling and helps it brown lightly.
The step that matters
Stir in the eggs one at a time without beating. Adding eggs gradually and mixing gently lets each one blend in fully, giving a smooth, stretchy dough. Overbeating or adding eggs too fast can make the dough thin, so the puffs fail to rise and hold their shape.
Swap the lemon
