Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Petits Choux

Oven, in the book's wordsA moderate oven

Ingredients

Directions

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

Make the paste

  1. Combine butter, water, sugar, salt, and vanilla in a saucepan.

  2. Bring the mixture to a boil.

  3. Stir in flour and continue stirring until it forms a tough paste.

  4. Remove from heat and gradually mix in the eggs until well incorporated.

Bake and fill

  1. Butter a baking sheet and place the paste in walnut-sized pieces.

  2. Brush the pieces with egg wash, sprinkle with sugar, and bake at 350°F (175°C) until golden.

  3. Once cooled, cut a lid on top of each and fill with jam or marmalade before serving.

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

What each ingredient does

Eggs
Add structure and moisture, and help the paste puff and set as it bakes.
Flour
Gives the paste body so it holds its shape when piped or dropped onto the sheet.
Butter
Adds richness and tenderness to the paste.

The step that matters

Mixing in the eggs off the heat. Eggs added to a paste that is still very hot can scramble, and a paste that is too hot or too cool will not emulsify smoothly. Adding them gradually, off the heat, lets the dough absorb them evenly so it can rise and hold its shape in the oven.

Swap the vanilla

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

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

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