Bleu d'Auvergne, Seared Pear & Walnut Rough-Puff Allumettes

Instructions

1. 1

   In a wide mixing bowl, whisk together 250 g all-purpose flour and 1 tsp fine sea salt. Toss in 200 g unsalted European-style cultured butter. Using your thumbs and fingertips, flatten each cube into a thin pebble—do not rub into sand. The butter must remain visibly layered and flat. Drizzle in 110 ml ice water and toss lightly with a bench scraper until a shaggy, dry-looking dough forms with dry pockets of flour.

   10 min

   Tip: Visible butter leaves equal shattered pastry sheets later. If the butter starts warming up under your fingers, throw the bowl in the freezer for 5 minutes.

2. 2

   Tip the shaggy mass onto a lightly floured counter. Press into a rough rectangle, roll to roughly 8x16 inches, and give it a classic letter fold (fold the top third down and bottom third up, like business mail). Rotate 90 degrees and repeat the roll and letter fold once more. Wrap tightly in parchment and transfer to the freezer to chill rapidly.

   10 min

   Tip: That's two quick turns done in under five minutes. Don't worry if the dough looks slightly rough; lamination smooths out during resting.

3. 3

   While the pastry rests, heat a dry skillet over medium heat. Toast 50 g raw walnut halves until fragrant and golden, about 3 to 4 minutes, then tip onto a board. Wipe the skillet, add 1 tbsp olive oil, and increase heat to medium-high. Lay in 2 firm-ripe Bosc or Anjou pears in a single layer. Sear without moving for 2 minutes until caramelized at the edges, then flip for 30 seconds. Remove from the heat immediately to cool.

   10 min

   Tip: You want charred edges with firm centers, not mush. Overcooked pears will weep moisture onto your puff pastry.

4. 4

   Preheat your oven to 400°F (205°C) and line a large baking sheet with parchment paper. Pull the dough from the freezer. Roll it out on a lightly floured surface into a 10x14-inch rectangle, about 1/8-inch thick. Trim 1/4-inch off all four edges with a sharp chef's knife or pizza wheel to expose the laminated butter layers. Cut the rectangle down the center lengthwise, then crosswise into 12 even fingers (allumettes) measuring roughly 2x5 inches each.

   10 min

   Tip: Always cut straight down with a sharp blade; dragging or sawing pinches the laminated edges shut and prevents maximum puff.

5. 5

   Transfer the pastry fingers onto the prepared sheet, leaving an inch between each. Brush the surface lightly with 1 egg whisked with water. Distribute 140 g Bleu d'Auvergne evenly down the center stripe of each allumette, leaving a 1/4-inch border bare. Lay 2 to 3 seared pear slices over the cheese. Scatter the toasted walnuts, 1.5 tsp fresh thyme leaves, 0.5 tsp freshly cracked black pepper, and 0.5 tsp flaky sea salt over top.

   10 min

   Tip: Keeping the outer edges clear allows the uncovered pastry perimeter to puff sky-high around the savory core.

6. 6

   Bake at 400°F (205°C) for 22 to 25 minutes, rotating the pan at minute 15, until the pastry edges are deeply browned, flaky, and dry to the touch, and the cheese is bubbling with toasted specks. Cool on the sheet pan for 5 minutes before transferring to a wire rack. Serve warm or room temperature.

   25 min

   Tip: Look for deep chestnut color on the pastry edges. Pale rough-puff is soggy rough-puff.
