Petits Choux

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.

Make the paste

  1. In a saucepan, bring the water and butter to a boil.

  2. Stir in the flour until a smooth paste forms.

  3. Remove from heat and let cool slightly.

  4. Gradually stir in the egg yolks and egg white, beating well.

  5. Add salt, sugar, and flavoring essence.

Bake and cool

  1. Drop spoonfuls of the paste onto a buttered baking sheet, spaced an inch apart.

  2. Bake in a moderate oven (350°F / 175°C) until light brown.

  3. Cool on a wire rack.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Flour
Starch that thickens the paste and gives the puffs their structure once baked.
Eggs
Add moisture and protein that set during baking, helping the puffs rise and hold their shape.
Butter
Adds fat for tenderness and flavor, and melts into the boiling water to enrich the paste.

The step that matters

Beating in the eggs. Eggs must be added gradually and beaten well so the paste becomes smooth and glossy. Adding them too quickly can break the emulsion, leaving a runny paste that will not puff properly.

Swap the vanilla

How well each one fits the dish's main ingredients (egg, butter, flour, sugar):

  1. Raisinfits better
  2. Vanillathe original
  3. Figfits less well
  4. Lemonfits less well

Fit is the average pairing score against egg, butter, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
