Petits Fours

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.

Prepare the dough

  1. Preheat the oven to 400°F (200°C).

  2. On a clean surface, make a well in the flour and add the butter and salt.

  3. Gradually mix in water to form a dough that can be rolled out.

Shape and glaze

  1. Roll the dough to ¼ inch thick and cut into 4-inch rounds.

  2. Glaze the tops with beaten egg and sprinkle with coarse sea salt.

  3. Prick the dough with a fork and place on a lightly greased baking sheet.

Bake

  1. Bake until lightly golden.

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

What each ingredient does

Flour
Forms the gluten network that gives the dough its structure once water is added.
Butter
Adds fat that shortens gluten strands, giving the pastry a tender, crumbly texture.
Egg
Brushed on top, it promotes browning and gives the tops a glossy finish.

The step that matters

Gradually mix in water. Adding water slowly lets the flour absorb just enough liquid to form a rollable dough. Too much water makes the dough sticky and tough, while too little leaves it dry and cracked when rolled.
