Shu Mai (Steamed Chinese Dumplings)

Ingredients

2 tablespoons soy sauce ½ teaspoon unflavored powdered gelatin 1 pound boneless country-style pork ribs, cut into 1-inch pieces½ pound shrimp, peeled, tails removed and halved lengthwise (see note)¼ cup water chestnuts, chopped4 dried shiitake mushroom caps (about ¾ ounce), soaked in hot water 30 minutes, squeezed dry, and cut into ¼-inch dice2 tablespoons cornstarch 2 tablespoons minced fresh cilantro leaves 1 tablespoon toasted sesame oil 1 tablespoon Chinese rice cooking wine (Shaoxing) or dry sherry1 tablespoon rice vinegar 2 teaspoons sugar 2 teaspoons grated ginger ½ teaspoon table salt ½ teaspoon ground black pepper 1 (1 pound) package 5 ½ inch square egg roll wrappers (see note)¼ cup carrot, finely grated (optional)

Before You Begin

Do not trim the excess fat from the ribs; it contributes flavor and moistness. Use any size shrimp except popcorn shrimp; there’s no need to halve shrimp smaller than 26 to 30 per pound before processing. Shu mai may be frozen for up to three months; cook them straight from the freezer for an extra 5 minutes or so. Serve shu mai with store-bought chili oil or make your own (see related recipe).

Instructions

  1. Combine soy sauce and gelatin in small bowl. Set aside to allow gelatin to bloom, about 5 minutes.
  2. Meanwhile, place half of pork in food processor and pulse until coarsely ground into approximate 1/8-inch pieces, about ten 1-second pulses; transfer to large bowl. Add shrimp and remaining pork to food processor and pulse until coarsely chopped into approximate ¼-inch pieces, about five 1-second pulses. Transfer to bowl with more finely ground pork. Stir in soy sauce mixture, water chestnuts, mushrooms, cornstarch, cilantro, sesame oil, wine, vinegar, sugar, ginger, salt, and pepper.
  3. Divide egg roll wrappers into 3 stacks (6 to 7 per stack). Using 3-inch biscuit cutter, cut two 3-inch rounds from each stack of egg roll wrappers (you should have 40 to 42 rounds). Cover rounds with moist paper towels to prevent drying.
  4. Working with 6 rounds at a time, brush edges of each round lightly with water. Place heaping tablespoon of filling into center of each round. Following illustrations below, form dumplings, crimping wrapper around sides of filling and leaving top exposed. Transfer to parchment-lined baking sheet, cover with damp kitchen towel, and repeat with remaining wrappers and filling. Top center of each dumpling with pinch of grated carrot, if using.
  5. Cut piece of parchment slightly smaller than diameter of steamer basket and place in basket. Poke about 20 small holes in parchment and lightly coat with nonstick cooking spray. Place batches of dumplings on parchment liner, making sure they are not touching. Set steamer over simmering water and cook, covered, until no longer pink, 8 to 10 minutes. Serve immediately with chili oil.

Why This Recipe Works

For moist and tender meat in our Shu Mai recipe, we used our food processor to grind boneless country-style ribs in two batches: one chunky and one fine. Once combined in the steamed dumplings’ filling, the smaller pieces helped hold the larger bits together and added a pleasant textural contrast. We used a mixture of powdered gelatin and cornstarch to keep our shu mai’s filling moist and tender, and we flavored it with cilantro, ginger, and Shaoxing wine. For wrappers, we used square egg roll skins, which we cut into rounds with a biscuit cutter. Finally, we garnished each dumpling’s center with finely grated carrot and served our shu mai with a quick dash of chili oil.
