Oven, in the book's wordsA medium oven

Ingredients

Directions

The book says “a medium oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dough

  1. Heat milk and butter in a saucepan until boiling.

  2. Stir in flour.

  3. Mix until smooth and it leaves the sides of the pan.

  4. Remove from heat.

  5. Beat in the eggs without pre-beating them.

Shape and bake

  1. Drop tablespoonfuls onto greased baking sheets, leaving space between them.

  2. Brush with egg yolk mixed with a little water.

  3. Sprinkle with sugar.

  4. Bake at 350°F (175°C) for 31 minutes or until dry and hollow.

  5. Let cool.

Fill and flavor

  1. Make an opening in the side to fill with whipped cream or custard.

  2. Whip cream with powdered sugar.

  3. Flavor with vanilla or orange.

Make the custard

  1. Mix reserved milk with flour until smooth.

  2. Add to hot milk and stir until thick.

  3. Beat together reserved milk, eggs, and sugar for custard filling.

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

What each ingredient does

Flour
Gives the dough its structure so the puffs can hold their shape and hollow centre.
Eggs
Add structure and steam that lifts the puffs, and set the custard filling.
Butter
Adds fat that softens the dough, giving a tender shell.
Milk
Provides liquid that turns to steam in the oven, helping the puffs rise.
Cream
Adds richness and a light, soft texture to the filling.

The step that matters

Bake until dry and hollow. Shells must be baked until fully dry. Underbaked puffs still hold steam and moisture, so they collapse as they cool and become soggy inside.
