Instructions

FOR WRAPPERS: In a food processor fitted with the metal blade, combine the 2 cups flour and salt and pulse once to mix. With the motor running, slowly pour in the boiling water. Continue to process until a rough ball forms and the dough pulls away from the sides of the work bowl, 15-20 seconds. Transfer to a lightly floured work surface. Knead until smooth and no longer sticky, about 2 minutes. Cover with a kitchen towel and let rest for 30 minutes. FOR FILLING: Place the cabbage and spinach in a kitchen towel, wring out the excess liquid and place in a bowl. Add all the remaining filling ingredients and stir until combined. Cover and refrigerate until ready to use. Uncover the dough and knead briefly. Cut in half. Roll out one half about 1/8 inch thick. Using a round cookie cutter 3 1/2 inches in diameter, cut out rounds. Set the rounds aside, lightly covered with the kitchen towel. Repeat with the remaining dough and all scraps. FOR SAUCE: Stir together the vinegar and soy sauce. Add chili oil to taste. Set aside. FOR POTSTICKERS: Put 1 tablespoon of the filling in the middle of a dough round. Fold the round in half and pinch the edges together at one end of the arc. Starting from that point, make 6 pleats or tucks along the curved edge to enclose the filling. As each potsticker is made, place seam-side up on a baking sheet, pressing down gently so it will sit flat. Cover with the kitchen towel and continue forming and placing the potstickers on the baking sheet until all are made. Heat a 9-inch nonstick frying pan over medium-high heat. When hot, add about 2 teaspoons vegetable oil. Arrange 8-10 potstickers, seam side up and just touching, in a spiral in the pan. Fry until the bottoms are browned, about 1 minute. Add water to come halfway up the sides of the potstickers and bring to a boil. Immediately cover, reduce the heat to low and steam-cook for 8 minutes, adding more water if necessary to keep the pan wet. Uncover, increase the heat to hi
