  2. Dredge flour under the paste.

  3. Roll it out to about ½ inch thick.

  4. Keep it square at both ends.

  5. Fold the paste in thirds.

  6. Roll it out again in the opposite direction.

  7. Repeat the folding process.

  8. Repeat the rolling process.

  9. Chill again for 15 minutes.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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

All-purpose flour
Forms the gluten structure that holds the dough together and gives it strength to roll.
Unsalted butter
Forms the separate fat layers that steam and lift the pastry during baking.
Egg yolk
Adds richness and helps bind the dough.
Cold water
Hydrates the flour to form the dough while keeping the fat firm.

The step that matters

Keep the butter in a cold, separate layer. If the butter softens or blends into the dough, the layers fuse and the pastry will not puff. Chilling between rolling and folding keeps the fat solid so it creates distinct layers that steam apart in the oven.
