Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Make the dough

  1. Make a hole in the flour.

  2. Add a pinch of salt.

  3. Mix with cold water until a dough forms, using about ½ cup.

Laminate

  1. Roll the dough to ¼ inch thick.

  2. Spread ½ pound of butter evenly over the dough.

  3. Fold the dough in four.

  4. Roll it out again.

  5. Fold it four more times.

  6. Use flour to prevent sticking.

Shape and bake

  1. Cut with a pastry cutter.

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

  3. Bake in a 400°F (200°C) oven for 15 minutes without opening the door for the first 10 minutes.

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.
Butter
Forms separate layers that steam apart during baking, creating flakiness.
Cold water
Hydrates the flour to form the dough while keeping the butter firm.
Egg yolk
Gives the surface a glossy golden browning when brushed on before baking.

The step that matters

Spreading the butter and folding. The butter must stay cold and be spread into an even layer, so that the dough and butter form distinct thin layers. If the butter softens and blends in, the layers are lost and the pastry will not puff.
