Blistered Zucchini & Comté Rough-Puff Bandes

Instructions

1. 1

   In a large bowl, toss 250 g all-purpose flour and 1 tsp fine sea salt together. Add 200 g unsalted cultured butter. Coat the butter cubes in flour, then press each cube flat between your thumb and forefingers into shaggy sheets. Drizzle in 100 ml ice water and mix with a fork until the dough barely clumps together.

   10 min

   Tip: Do not knead until smooth! You want visible, cold butter chunks; this is what creates lacy, shatteringly flaky layers without full French lamination.

2. 2

   Tip the shaggy dough onto a work surface, shape into a rough rectangle, wrap tightly in plastic, and chill in the refrigerator.

   30 min

   Tip: Let time do the work. Cold butter is non-negotiable for lift.

3. 3

   While dough rests, slice 2 medium zucchini paper-thin using a mandoline. Toss with 1 tsp kosher salt in a colander set over a bowl. Let sit to draw out liquid.

   15 min

   Tip: Excess moisture is the enemy of crisp dough. Skimping here yields a soggy bottom tight like a bad alibi.

4. 4

   Unwrap the dough on a lightly floured surface. Roll into a 6x18-inch rectangle. Fold the bottom third up and top third down like a letter (tour simple). Turn dough 90 degrees, roll out again to 6x18 inches, and repeat the letter fold. Wrap and chill for 20 minutes.

   15 min

   Tip: Two quick folds give you 90% of traditional puff pastry layers in a fraction of the time.

5. 5

   Preheat your oven to 425°F (220°C) with a heavy baking sheet lined with parchment inside.

   20 min

   Tip: Preheating the sheet tray creates an instant blast of heat that sets the bottom crust instantly.

6. 6

   Transfer salted zucchini to a clean kitchen towel or cheesecloth. Squeeze firmly to wrung out every drop of moisture. Toss squeezed zucchini ribbons with 1 tbsp fresh thyme leaves and 1/2 tsp black pepper.

   10 min

   Tip: Don't skip this: squeeze until the zucchini feels nearly dry to the touch.

7. 7

   Roll chilled dough into a 10x14-inch rectangle, about 1/4-inch thick. Cut lengthwise into four long 2.5x14-inch strips (bandes). Spread 2 tbsp Dijon mustard down the center of each strip, leaving a 1/2-inch border. Top with 120 g Comté cheese and layer the dry zucchini ribbons down the length.

   12 min

   Tip: Keeping a border gives the puff room to rise tall around the savory filling.

8. 8

   Whisk 1 large egg with 1 tbsp heavy cream. Brush dough borders generously with egg wash. Carefully slide parchment with assembled bandes onto the preheated hot baking sheet. Bake at 425°F for 22-25 minutes until pastry is puffed, deeply bronzed, and edges are blistered.

   25 min

   Tip: Look for a deep mahogany-gold color; pale pastry lacks flavor and crunch.

9. 9

   Remove from oven, sprinkle warm pastries with 1 tsp lemon zest and 1/2 tsp flaky sea salt. Let cool on a wire rack for 5 minutes before serving warm.

   3 min

   Tip: The hit of lemon zest cuts right through the buttery richness of the pastry and Comté.
