1 (14-ounce) package all-butter puff pastry
1 egg, beaten
Preheat oven to 425°F.
In a heavy-bottomed pan over medium-high heat, toast the dried chiles, Sichuan peppercorn, white peppercorn, black cardamom, and star anise. The spices are done when they are super fragrant and have darkened slightly. In a spice grinder or mortar and pestle, grind to a fine powder with the bay leaf. Set aside.
In a sauté pan over medium-high heat, melt the butter and gradually add in the flour. Vigorously whisk and cook until a golden roux has developed. Add the onion, garlic, and ginger; cook until translucent. Add the broad bean chili paste and spice mixture, sauté until fragrant. Add the green bell pepper and celery; cook for 2 minutes. Stir in crawfish, Shaoxing wine, and soy sauce; cook for another minute. Pour in the heavy cream, and allow to thicken.
Divide the mixture between 4 (8-ounce) ramekins set on a rimmed baking sheet. Lay the puff pastry dough on a lightly floured cool surface. Dust the top of the dough with a little flour. Gently roll across the seams and bumps to even out the pastry, and cut out 4 (4 1/2-inch) circles. Brush the edges of the ramekins with egg. Place 1 circle over each and press to seal. Brush the tops and sides of the pastry with more egg. Bake for 20 to 25 minutes, until golden -rown. Serve immediately.
