Flour your work surface lightly and roll the dough, or pieces of it, about 1/8-inch thick (too thin and the dough will tear as you fill the dumplings). Cut out circles with a 3-inch round cutter. Cover the dough with a side towel or piece of plastic wrap
as you work.
Have a small bowl of water next to you. Place a scant tablespoon of filling in the middle of a dough circle, and press it so that it spreads slightly toward the side edges of the dough
. Using your fingertip or a small pastry brush
, wet the edge of the dough. Fold the dough up around the filling so that the filling sits on the work surface-that's the bottom of your dumpling-and the seam is between your fingers. Pleat the dough that is facing you, about 6 times, pressing it against the back to seal-only the front of the dumpling should be pleated. The corners of the dumpling
should curl slightly away from you, toward the unpleated side.
Heat a skillet, just large enough to accommodate the number of dumplings you want to cook over high heat. Add a thin coating of oil, heat, then add the dumplings in concentric circles. They should be touching. Cook until the bottoms are golden brown, 3 or 4 minutes (reduce the heat if they are browning too quickly). Add enough water to come about 1/4 of the way up the sides of the dumplings-it will spatter. Cover the skillet, adjust the heat so that the water is simmering, and cook for about 7 minutes. Uncover the skillet and, if there is water left, let it cook off. Check the dumpling bottoms-if they need to brown a bit more, let them, adding a bit more oil if necessary.
Serve the dumplings immediately, drizzled with some dipping sauce and garnished with cilantro and lime wedges.
