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 Puff

Oven, in the book's wordsA fairly hot oven

Ingredients

Directions

The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the pastry

  1. Boil ½ cup hot water and ½ cup butter in a saucepan.

  2. Stir in 1 cup all-purpose flour while boiling.

  3. Let the mixture cool, then stir in 4 eggs one at a time without beating.

Shape and bake

  1. Drop spoonfuls of the mixture onto a baking sheet.

  2. Bake in a fairly hot oven at 400°F (200°C).

Make the cream

  1. For the cream, combine 1 pint milk, 3 tablespoons flour, 1 egg, and ½ cup sugar in a saucepan.

  2. Cook until thickened, then let cool before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Starch and gluten give the paste the structure to hold its shape and puff.
Eggs
Set the paste as it bakes and their steam helps the puffs rise hollow.
Butter
Adds fat that enriches the paste and gives a tender, rich texture.
Milk
Forms the liquid base of the cream, which thickens as its starch gelatinizes.
Sugar
Sweetens the cream and adds body to its flavor.

The step that matters

Adding the eggs to the paste. If the paste is still hot, the eggs can scramble. Stirring them in gently, one at a time, keeps the dough smooth and stiff enough to hold its shape and rise.
