Shrimp Potstickers and Scallion Dipping Sauce

For the Filling:

• 1

  Toss cabbage and salt in colander or mesh strainer set over medium bowl. Let stand until cabbage begins to wilt, about 20 minutes; press cabbage gently with rubber spatula to squeeze out excess moisture. Combine cabbage and all other filling ingredients in medium bowl and mix thoroughly. Cover bowl with plastic wrap and refrigerate until mixture is cold, at least 30 minutes and up to 24 hours.

  2. Place 4 wrappers flat on work surface (keep remaining wrappers covered with plastic wrap). Place one slightly rounded tablespoon filling in center of each wrapper. Using pastry brush or fingertip, moisten edge of wrapper with water. Fold each wrapper in half; starting in center and working toward outside edges, pinch edges together firmly to seal, pressing out any air pockets. Position each dumpling on its side and gently flatten, pressing down on seam to make sure it lies flat against work surface. Repeat to form 24 dumplings. (Filled dumplings can be refrigerated overnight in single layer on baking sheet wrapped tightly with plastic wrap.)

  3. Add 2 teaspoons oil to 12-inch nonstick skillet and quickly spread oil with paper towel to distribute evenly. Arrange 12 dumplings in skillet, lying flat on one side, with all seams facing same direction, overlapping just slightly, if necessary. Place skillet over medium-high heat and cook, without moving, until dumplings are golden brown on bottoms, about 5 minutes. Reduce heat to low, add 1/2 cup water to skillet, and cover immediately. Cook, covered, until most of water is absorbed and wrappers are slightly translucent, about 10 minutes. Uncover skillet and increase heat to medium-high; cook, without stirring, until dumpling bottoms are well browned and crisp, 3 to 4 minutes more. Turn off burner and slide dumplings from skillet onto double layer paper towels, browned side down, to blot excess oil. Transfer to platter and serve immediately with Scallion Dipping Sauce. Let skillet cool until just warm, then wipe skillet clean and repeat with remaining dumplings and oil.
