Water Dough (Outer Layer):

  • 5 oz (1 cup) all-purpose flour
  • 1 ½ tsp. sugar
  • ¼ tsp. kosher salt
  • 1 T. cold unsalted butter cut into ½-inch pieces
  • 5 T. warm water

Short Dough (Inner Layer):

  • 3 ¾ oz (¾ cup) all-purpose flour
  • 6 T. cold unsalted butter cut into ½-inch pieces


  • 2 T. water
  • 1 T. sugar
  • 1 T. hoisin sauce
  • 1 tsp. oyster sauce
  • ½ tsp. soy sauce
  • ½ tsp. toasted sesame oil
  • 2 tsp. peanut or vegetable oil
  • ¼ cup finely chopped onion
  • 1 tsp. cornstarch dissolved in 1 T. water
  • 4 oz. char siu (Chinese BBQ pork) finely diced (homemade or store-bought)


  • 1 egg beaten with 1 T. water
  • 1 T. sesame seeds


  • To make the water dough, combine the flour, sugar, and salt in a food processor and pulse 2 to 3 times. Sprinkle in the pieces of butter and process 10 more seconds until the mixture looks like coarse meal. Alternatively, put ingredients in a mixing bowl and use your fingers in a quick rubbing motion to combine flour and butter.
  • Transfer mixture to a bowl (if you used food processor method), make a well in the center, and work in the water 1 tablespoon at a time. Use a wooden spoon to stir into a ragged mass. Transfer to a lightly floured work surface and gently knead for about 2 minutes to create a soft, smooth, and slightly elastic dough. Pressing your finger in the dough should cause the dough to slowly bounce back, leaving a faint impression. Cover with plastic wrap and set aside at room temperature to rest for 20 to 30 minutes.
  • Meanwhile, make the short dough. Put the flour in the food processor and sprinkle in the butter. Process for 10 seconds to blend and generate a mealy, lumpy, very soft mixture. Transfer to the same bowl as before, and use the wooden spoon to mix and combine well. Alternatively, put the ingredients in the bowl and use your fingers or the back of the wooden spoon to mash together until no flour is visible. It will resemble soft cookie dough.
  • Gather and pat the dough on a lightly floured surface into a 3-by-4-inch rectangle. Set aside. Return the water dough to the lightly floured work surface and roll it out into a 5-by-8 ½-inch rectangle, with one long edge toward you (like a landscape photo). Place the short dough in the center of the water dough, with one short edge toward you (like a portrait photo). Fold the sides of the water dough over the short dough with the edges overlapping slightly (like enclosing a photo in a letter). Press the overlapping edges and both ends to seal in the short dough completely. Roll out in the direction of the folds to make a rectangle about 6-by-18-inches. Fold the dough into thirds to form a 6-inch square. Cover the dough with plastic wrap and refrigerate for 30 minutes.
  • Unwrap the dough and roll it out again in the same direction to make a 6-by-18-inch rectangle as before. Fold in thirds, wrap, and refrigerate for another 30 minutes. Repeat the rolling and folding processes once more (that’s 3 times total). Cover the dough with plastic wrap and refrigerate it at least 30 minutes, and up to 1 day ahead, before the final rolling and shaping.
  • To make the filling, in a small bowl, stir together the water, sugar, hoisin sauce, oyster sauce, soy sauce, and sesame oil, and set aside. Heat a medium skillet over medium heat. Add the oil. When it is almost smoking, add the onion and stir-fry for 3 minutes or until translucent. Stir the flavoring sauce into the onion and heave for 30 seconds or until bubbly. Give the cornstarch mixture a final stir and add to the skillet. Cook for 30 seconds longer, or until the sauce has thickened. Stir in the char siu and remove from the heat. Transfer the filling to a large plate and divide into 12 portions. Cool to room temperature.
  • Roll out the prepared dough into a 13-inch square. Using a ruler, trim off the uneven edges to make a 12-inch square, then cut the dough in thirds crosswise and quarters lengthwise to make 12 (3-by-4-inch) rectangles.
  • Preheat the oven to 400 degrees F and line a baking sheet with parchment paper.
  • Place one portion of the char siu filling across the center of each rectangle in the 3-inch direction, leaving about ½-inch border on either side for sealing. Overlap the dough over the filling (like enclosing a photo in a letter). Press down to seal in the filling on all sides. Flip the pastry over so the seal is on the bottom, and use the tines of a fork to seal the short edges. Place on the baking sheet. Repeat with the remaining dough and filling, spacing pastries 1-inch apart on the baking sheet. At this point, the unbaked pastries may be covered and frozen until firm and then transferred to a zip-top freezer bag. Place frozen pastries on a baking sheet as above and let them thaw 30 minutes before proceeding.
  • Brush the pastries with the egg wash, then sprinkle them with sesame seeds. Bake for 25 to 30 minutes, or until golden. Cool briefly on a wire rack. These are best served warm, but are also delicious at room temperature.
