Very Rich Puff Paste

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

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

  2. Dry the flour by placing it near the fire for a short time.

Make the pastry

  1. Mix equal amounts of butter and flour until well combined.

  2. Fold and roll the mixture five or six times to create layers.

  3. If desired, mix in a beaten egg for added richness.

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

What each ingredient does

Butter
Forms separate fat layers that help the pastry rise and become flaky when baked.
Flour
Provides the structure that holds the layers together as the pastry sets.

The step that matters

Fold and roll the mixture five or six times. Each fold stacks thin layers of butter and dough. If the butter softens and blends into the flour, the layers merge and the pastry loses its flaky rise.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
