Café-Case Mushroom & Gruyère Rough-Puff Twists (Porcini Dust + Peppery Honey)
I made these twists because I love the vitrine (café display case) moment—those glossy, laminated things you point at like you’re ordering confidence. But I don’t love the $9 price tag or the fact that half of them eat like dry cardboard by noon.
The inspiration was a mushroom–Gruyère feuilleté I used to grab in Paris between classes: hot paper bag, cold fingers, buttery flakes on my coat. In the Bay Area, I started packing snacks for long bakes and long drives, and I wanted something that traveled without turning sad. These do. All edges, maximum shatter, minimal fuss.
What makes them special to me is the contrast: a jammy cremini–shallot duxelles (mushroom mince cooked down until spreadable) against rough-puff layers that bake crisp, not tight like a bad alibi. Porcini “dust” is the mic drop—tiny effort, huge aroma. And that black-pepper honey? Sweet heat, café glam.
Make it yours: swap Gruyère for Comté or sharp cheddar, add thyme or lemon zest, or fold in chopped walnuts for crunch.
Cami’s shortcut note: rough puff is safe for weeknights because the fridge does the work.
Don’t skip this: cook the duxelles until it’s dry—no puddles, or your layers won’t flake.

Café-Case Mushroom & Gruyère Rough-Puff Twists (Porcini Dust + Peppery Honey)
These are crisp, laminated pastry twists stuffed with a jammy cremini–shallot duxelles and a salty snow of Gruyère. They bake up all edges—maximum shatter, minimal fuss—and they travel like a dream for commutes, hikes, or desk lunches. I finish them with a whisper of porcini “dust” and (optional but excellent) warm black-pepper honey for that café-case glam without the café price tag.

Ingredients
- 250 g All-purpose flour(plus extra for dusting)
- 6 g Fine sea salt(about 1 tsp)
- 5 g Granulated sugar(1 tsp; helps browning, not sweetness)
- 225 g Unsalted cultured butter, cold(cut into 1 cm cubes; keep refrigerated)
- 140 g Ice water(start with 120 g; add as needed)
- 10 g Apple cider vinegar(2 tsp; tenderizes, helps flake)
- 450 g Cremini mushrooms(finely chopped (or pulse in food processor))
- 10 g Dried porcini mushrooms (optional)(grind to powder or crumble very fine)
- 1 Shallot(large, finely minced)
- 2 cloves Garlic(microplaned or minced)
- 15 g Olive oil(1 tbsp)
- 25 g Unsalted butter(for the filling)
- 2 tsp Fresh thyme leaves(or 1 tsp dried)
- 1 tsp Black pepper(freshly ground, plus more to finish)
- 10 g Soy sauce(2 tsp; deepens savoriness)
- 15 g Dijon mustard(1 tbsp; optional but very good)
- 60 g Crème fraîche or cream cheese(binds the filling; keeps it lush)
- 120 g Gruyère(coarsely grated (Comté also great))
- 1 Egg(for egg wash)
- 15 g Water(1 tbsp, for egg wash)
- 1 pinch Flaky salt(to finish)
- 40 g Honey (optional)(2 tbsp, for serving)
- 1/2 tsp More black pepper (optional)(to warm into the honey)
- 1/2 teaspoon Porcini powder(Optional, mentioned in the egg wash step as a sprinkle)
Instructions
- 1
Make the rough puff dough: In a large bowl, whisk 250 g All-purpose flour, 6 g Fine sea salt, and 5 g Granulated sugar. Add 225 g Unsalted cultured butter, cold cubes and toss to coat. Press each cube flat between your fingers (quick, not precious)—you want big shards of butter, not sand.
8 min
Tip: If your kitchen is warm, chill the bowl 10 minutes first. Cold butter is the whole game.
- 2
Add ice water + vinegar. Drizzle in 140 g Ice water and 10 g Apple cider vinegar. Toss with a fork until shaggy; add more water 1 tbsp at a time only if you still have dry flour at the bottom. Squeeze a handful: it should hold together with visible butter pieces.
3 min
Tip: Too wet = tough and puffy, not flaky. Stop as soon as it clumps.
- 3
Do the quick folds (lamination-lite): Turn the dough onto a lightly floured counter. Pat into a rough rectangle. Roll to about 20 x 35 cm. Fold like a letter into thirds. Rotate 90°, roll again, fold again. Wrap and chill 30 minutes.
10 min
Tip: If butter starts to smear, stop and chill. Smear = lost layers.
- 4
Fold twice more: Repeat the roll-and-letter-fold two more times (so 4 folds total). Wrap and refrigerate at least 2 hours, or overnight.
10 min
Tip: This is the make-ahead method: the fridge sets layers and relaxes gluten. Let time do the work.
- 5
Cook the mushroom filling (duxelles-style): Heat 15 g Olive oil + 25 g Unsalted butter in a wide skillet over medium-high. Add 450 g Cremini mushrooms and a big pinch of salt. Cook, stirring, until they dump liquid, then keep going until the pan is dry and the mushrooms are browned and pasty.
14 min
Tip: Non-negotiable: drive off the water. Wet filling = soggy pastry and tight like a bad alibi.
- 6
Season and bind: Add 1 Shallot and cook 2 minutes. Add 2 cloves Garlic, 2 tsp Fresh thyme leaves, 1 tsp Black pepper; cook 30 seconds. Stir in 10 g Soy sauce. Off heat, cool 10 minutes, then mix in 15 g Dijon mustard and 60 g Crème fraîche or cream cheese. Chill until spreadable (15–20 minutes).
25 min
Tip: Cooling matters: warm filling melts butter layers before the oven can set them.
- 7
Build the twists: Heat oven to 220°C / 425°F. Line two baking sheets with parchment. Roll dough to about 3 mm thick into a 25 x 40 cm rectangle. Spread mushroom filling in a thin, even layer over half the rectangle. Sprinkle 90 g Gruyère over the filling. Fold the bare half over like a book; gently press to seal.
12 min
Tip: Keep the layer thin—think ‘buttered toast,’ not ‘lasagna.’ Thin = crisp.
- 8
Cut and twist: Trim edges. Cut into 12–14 strips (about 2 cm wide). Twist each strip 3–4 turns and place on trays with space. Freeze 10 minutes to firm up.
15 min
Tip: Freezing is your safety net: firm dough twists cleanly and bakes higher.
- 9
Egg wash + bake: Whisk 1 Egg with 15 g Water. Brush twists lightly (don’t flood). Sprinkle remaining 120 g Gruyère, 1 pinch Flaky salt, and (optional) 1/2 teaspoon Porcini powder. Bake 15 minutes, rotate trays, then bake 6–10 minutes more until deeply golden and crisp at the edges.
24 min
Tip: Color is flavor. You want ‘brown bakery’ not ‘beige buffet.’
- 10
Finish and pack: Cool 10 minutes on the tray, then move to a rack. Eat warm, or cool completely before packing. Optional: warm 40 g Honey with 1/2 tsp More black pepper and serve for dipping (sweet-salty, very café).
12 min
Tip: Packing tip: once fully cool, store in a paper bag inside a container to keep crispness.
Chef's Notes
Why it works: rough puff gives you real layers without the all-day laminating schedule. The vinegar keeps the dough tender, and the chill between folds keeps butter in distinct sheets so it bakes into lift. Cami’s shortcut note: Make the dough and the mushroom filling up to 3 days ahead. Day-of, you’re just rolling, twisting, baking. You can also shape the twists, freeze solid on a tray, then bag them—bake from frozen at 220°C / 425°F, adding 3–5 minutes. Don’t skip this: cook the mushrooms until the pan is dry and the mixture turns jammy. Mushrooms are basically little water balloons; if you don’t pop and evaporate them now, they’ll do it inside your pastry and steal your crunch. Troubleshooting: If your twists leak butter, your dough got too warm during rolling—next time, chill 15 minutes mid-roll. If they’re not flaky, you likely overmixed the dough at the start or added too much water; keep it shaggy and stop early.
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.
