Roast Pork Buns

I was just sifting through some photos I took a few months ago and saw these pictures of the most delicious, melt-in-your-mouth, roast pork belly I ever made.  I remember it was so rich and so good, and I probably ate most of it by myself.  The pictures reminded me of a post I started and never finished it, so here it is.

Brined & Roasted Pork
1/2 c. kosher salt
1/2 c. sugar
4 1/2 c. water, divided
2 1/2 lb skinless boneless pork belly, cut into quarters
1/2 c. reduced-sodium chicken broth 

Steamed Buns
1 c. warm water (105-115°F), divided
1/2 tsp. active dry yeast
3 T. sugar plus a pinch
2 T. nonfat dried milk
3 1/2 c. cake flour (not self-rising)
1 1/2 tsp. baking powder
Canola oil for greasing and brushing

Preparation

Brine pork:
Stir together kosher salt, sugar, and 4 cups water until sugar and salt have dissolved. Put pork belly in a large sealable bag, then pour in brine. Carefully press out air and seal bag. Lay in a shallow dish and let brine, chilled, at least 12 hours.

Make dough for buns while pork is brining:
Stir together 1/4 cup warm water with yeast and pinch of sugar. Let stand until foamy, 5 to 10 minutes. (If mixture doesn't foam, start over with new yeast.) Whisk in dried milk and remaining 3/4 cup warm water.

Stir together flour and remaining 3 tablespoons sugar in a bowl, then stir in yeast mixture (do not add baking powder yet) with a fork until a dough forms. Knead dough with your hands in bowl until all of flour is incorporated. Turn out dough onto a floured surface and knead, dusting surface and hands with just enough flour to keep dough from sticking, until dough is elastic and smooth but still soft, about 5 minutes. Form dough into a ball.  Put dough in an oiled large bowl and turn to coat. Cover with plastic wrap and let dough rise in a draft-free place at warm room temperature until doubled, about 2 hours.

Roast pork while dough rises:
Preheat oven to 300°F with rack in middle.

Discard brine and put pork, fat side up, in an 8- to 9-inch square baking pan. Pour in broth and remaining 1/2 cup water. Cover tightly with foil and roast until pork is very tender, about 2 1/2 hours. Remove foil and increase oven temperature to 450°F, then roast until fat is golden, about 20 minutes more. Cool 30 minutes, then chill, uncovered, until cold, about 1 hour.

Cut chilled pork across the grain into 1/4-inch slices. Chill slices in pan juices, covered, while making buns.

Make buns:
Punch down dough, then transfer to a lightly floured surface and flatten slightly into a disk. Sprinkle baking powder over center of dough, then gather edges of dough and pinch to seal in baking powder. Knead dough with just enough flour to keep dough from sticking until baking powder is incorporated, about 5 minutes. Return dough to bowl and cover with plastic wrap, then let dough stand 30 minutes.

Cut 16 (3- by 2-inch) pieces of wax paper.

Form dough into a 16-inch-long log. Cut into 16 equal pieces, then lightly dust with flour and loosely cover with plastic wrap. Roll out 1 piece of dough into a 6- by 3-inch oval, lightly dusting surface, your hands, and rolling pin. Pat oval between your palms to remove excess flour, then brush half of oval lightly with oil and fold in half crosswise (do not pinch). Place bun on a piece of wax paper on a large baking sheet and cover loosely with plastic wrap. Make more buns with remaining dough, then let stand, loosely covered, until slightly risen, about 30 minutes.  Set a large steamer rack inside skillet (or wok) and add enough water to reach within 1/2 inch of bottom of rack, then bring to a boil. Carefully place 5 to 7 buns (still on wax paper) in steamer rack (do not let buns touch). Cover tightly and steam over high heat until buns are puffed and cooked through, about 3 minutes. Transfer buns to a plate with tongs, then discard wax paper and wrap buns in kitchen towels (not terry cloth) to keep warm. Steam remaining buns in 2 batches, adding boiling-hot water to skillet as needed.

Return buns (still wrapped in towels) to steamer rack in skillet and keep warm (off heat), covered.

To Serve:
Preheat oven to 350°F with rack in middle. Heat sliced pork (in liquid in baking dish), covered, until hot, 15 to 20 minutes.

Brush bottom half of each bun with hoisin sauce, then sandwich with 2 or 3 pork slices and some cucumber and scallions.

Cooks' notes: ·Pork belly can be brined up to 24 hours.
·Pork can be roasted and sliced 2 days ahead and chilled (in liquid), covered.
·Buns can be steamed and cooled completely, then chilled, wrapped tightly in a double layer of plastic wrap, up to 1 day or frozen up to 1 week. (Thaw wrapped frozen buns in refrigerator.) Reheat buns, wrapped in a dampened kitchen towel and then tightly in foil, in a 350°F oven until soft and heated through, about 15 minutes.
