Wild Mushroom and Comté Rough-Puff Allumettes
I first fell for allumettes—matchstick pastries—in a tiny café near the Marais, where flaky pastry met salty cheese in a way that ruined me for standard appetizers. Years later in my Bay Area kitchen, I wanted that same high-end bakery feel without spending my entire Sunday laminating butter. We are not suffering for brunch, after all. That is where these Wild Mushroom and Comté Rough-Puff Allumettes come in. By using a weeknight rough-puff method, you get incredible, lacy layers with minimal effort. The secret is letting time do the work on your mushroom duxelles, cooking out every drop of moisture until it concentrates into an intensely savory paste. Roll it out, fold it in, and bake until deeply golden. Butter is not a garnish here, so use the good cultured stuff. Don't skip the final dusting of nutty Comté just before it hits the oven. Make it your own by swapping the mushrooms for caramelized onions or tossing in a handful of fresh thyme. It is café-level baking made entirely practical for your real-life schedule.

Timeline
Ingredients
- 200 g all-purpose flour(unbleached, chilled in the fridge for 10 minutes if your kitchen is warm)
- 0.5 tsp fine sea salt(divided)
- 170 g unsalted cultured butter(very cold, cut into 1/2-inch cubes)
- 80 ml ice water(about 1/3 cup; must be ice-cold)
- 280 g cremini or mixed wild mushrooms(about 10 oz, cleaned and very finely minced)
- 1 tbsp olive oil
- 1 shallot(medium, finely minced)
- 2 cloves garlic(grated or finely minced)
- 1 tbsp fresh thyme leaves(roughly chopped)
- 2 tbsp dry white wine(or dry white vermouth)
- 1 tbsp unsalted butter(for sautéing the duxelles)
- 0.25 tsp freshly cracked black pepper
- 85 g Comté cheese(finely grated, divided; Gruyère works equally well)
- 1 large egg(beaten with 1 tsp cold water for egg wash)
- 0.5 tsp flaky sea salt(such as Maldon, for finishing)
- 1 tbsp unsalted butter(for duxelles)
Instructions
- 1
In a wide mixing bowl, whisk 200 g all-purpose flour with 0.25 tsp fine sea salt. Toss in 170 g unsalted cultured butter. Using your fingers or a pastry cutter, press the butter cubes flat into rough flakes—do not rub them down into fine meal; large butter shingles create steam pockets. Drizzle in 80 ml ice water and toss lightly with a fork until a shaggy, uneven mass forms. Tip the mixture onto a lightly floured board, press into a rough rectangle, roll it out gently to roughly 6x12 inches, and fold into thirds like a business letter. Turn 90 degrees, roll once more, and repeat the fold. Wrap tightly and stash in the freezer for 15 minutes to drop the dough temp fast.

Tip: Butter is not a garnish, and it shouldn't melt before hitting the oven. Visible butter stripes mean flaky, lacy layers.

Set a wide stainless steel or cast-iron skillet over medium-high heat. Add 1 tbsp olive oil and 280 g cremini or mixed wild mushrooms along with the remaining 0.25 tsp fine sea salt. Sauté dry for 5 to 6 minutes without crowding until all extracted moisture evaporates and the mushrooms begin to brown. Lower heat to medium, stir in 1 shallot, 2 cloves garlic, 1 tbsp fresh thyme leaves, and 0.25 tsp freshly cracked black pepper. Cook for 2 minutes until sweet and fragrant, then deglaze with 2 tbsp dry white wine, scraping up any browned bits. Once the pan is dry, swirl in 1 tbsp unsalted butter. Spread the duxelles onto a plate and set in the fridge to cool completely.
12 min
Tip: Moisture is the enemy of lamination. Searing the mushrooms until dry ensures crisp bottoms instead of soggy pastry.

Position a rack in the center of your oven and preheat to 425°F (220°C). Line a large rimmed sheet pan with parchment paper.
3 min
Tip: A ripping-hot oven converts the water in your cold butter into instant steam, lifting the pastry into crisp ridges.

Retrieve the chilled rough puff. On a lightly floured surface, roll it into a clean 10x12-inch rectangle, roughly 1/8-inch thick. Trim ragged edges with a sharp knife. Cut the sheet in half crosswise to create two 10x6-inch slabs. Evenly spread the cooled mushroom duxelles over one slab, leaving a 1/4-inch clean border all around. Shower 60 g Comté cheese directly over the mushrooms. Lay the second pastry slab on top, pressing the edges lightly with your fingertips to seal. Place on your cutting board and use a very sharp chef's knife or pizza wheel to slice straight down into 10 slender batons (each about 1 inch wide by 6 inches long).
7 min
Tip: Never saw back and forth with your knife—press straight down to avoid pinching the laminated edges together.
- 5
Transfer the batons onto the prepared baking sheet, leaving about 1.5 inches of breathing room between them. Brush the pastry tops lightly with 1 large egg beaten with water, avoiding letting egg drip down the raw cut sides. Sprinkle the remaining 25 g Comté cheese and 0.5 tsp flaky sea salt along the center spine of each baton.
3 min
Tip: Egg wash pooling down the sides glues the layers shut and hinders rise. Keep the wash strictly on top.
- 6
Bake at 425°F (220°C) for 18 to 22 minutes until puffed, rigid, and deep amber-brown from edge to center, with bubbling cheese edges. Transfer the pan to a wire rack and let rest 5 minutes so the pastry sets and shatters cleanly.
20 min
Tip: If the tops brown before 16 minutes, your oven runs hot; drop heat to 400°F (200°C) to make sure the core bakes fully crisp.
Chef's Notes
Allumette is French for 'matchstick'—classic café pastry batons made for nibbling with crisp white wine or an afternoon coffee. The non-negotiable here is letting the mushroom duxelles cool before spreading it on the dough; warm mushrooms will melt the butter shingles instantly and murder your lift. We're not suffering for brunch or a 4 p.m. craving: rough puff takes ten minutes of active rolling, and the fridge does the heavy lifting.
Camille Roux
Café-level bakes, weeknight methods, zero compromise.
Camille “Cami” Roux was born in Paris with flour in her hair and a healthy skepticism of culinary dogma. She grew up around neighborhood boulangeries that treated crust and crumb like religion—but what stuck with her wasn’t rigid tradition. It was the quiet precision: good butter that actually tastes like milk, patient fermentation that builds flavor for free, and desserts that know when to stop before they get cloying. After moving to the Bay Area, Cami trained in a bread-and-pastry scene obsessed with texture, naturally leavened doughs, and seasonal fruit—Tartine energy, minus the martyrdom. She became known for loaves that sing when they cool, jammy tarts with clean edges, and “how is this so good?” weeknight pastries made with a few smart shortcuts. Her motto is high impact, low fuss: splurge where it counts (butter, salt, time), streamline the rest (sheet pans, one bowl, cold-proofing). If it doesn’t improve flavor or structure, it doesn’t earn a step.
