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 ↓
Custard Cream Pufes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the puff dough
In a pot, bring the boiling water and butter to a boil.
Stir in the flour and baking powder until combined.
Let the mixture cool, then add the beaten eggs and mix well.
Drop spoonfuls into muffin rings and bake at 400°F (200°C) for 30 minutes.
Make the custard
In another pot, boil the milk.
In a bowl, beat together 1 cup of flour, 1 cup of sugar, and 2 eggs.
Add this mixture to the boiling milk and cook for 3 minutes.
Fill and serve
Cut a hole in the top of each puff and fill with the cream, replacing the piece of crust.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the boiling water to add fat and richness to the dough.
- Flour
- Provides the structure that holds the puffs together as they bake.
- Eggs
- Add structure and moisture to the dough and thicken the custard.
- Baking powder
- Releases gas during baking so the puffs rise and turn hollow.
- Milk
- Forms the liquid base of the custard, giving it creaminess.
- Sugar
- Sweetens the custard filling.
The step that matters
Cook the custard after adding the egg mixture. Once the flour and egg mixture meets the boiling milk, it needs steady cooking so the starch thickens and the eggs set without curdling. Stopping too early leaves the filling thin.
