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
Heat butter and milk in a pan until boiling.
Add flour and mix well.
Let mixture cool, then mix in eggs and sugar.
Bake
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 fat and richness, giving the puffs a tender, flavorful crumb.
- Flour
- Provides the structure that holds the choux-style dough together as it bakes.
- Eggs
- Set the structure and help the puffs rise and hold their shape as they bake.
- Milk
- Supplies liquid that turns to steam in the oven, helping the puffs expand.
The step that matters
Let the mixture cool before adding eggs. If the dough is still hot, the eggs can scramble or cook partially, and the batter may thin too much to hold its structure and rise well.
“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.
