Soak mushrooms in ½ cup of cold water until they're soft, which should take about 30 minutes. After they're soaked, drain the water and squeeze the mushrooms to get rid of excess water.
Remove the mushroom stems and throw them away. Chop up the mushroom tops until you have about ½ cup.
In a medium-sized bowl, mix together the pork, water chestnuts, scallions, and the chopped mushrooms.
To the same bowl, add cornstarch, rice wine, soy sauce, ginger, oil, sugar, salt, pepper, and egg whites. Stir everything together until it's well mixed.
Take a dumpling wrapper and place 1 Tablespoon of the pork mixture onto the center of the wrapper, but leave a little border (about ⅛ inch) around the edge without any filling.
Fold the edges of the dumpling wrapper over the filling so that it's enclosed, except for a small opening at the top. Make sure the dumplings are shaped so they can stand up on their own.
Put the filled dumplings on a work surface that has been lined with parchment paper and lightly sprinkled with cornstarch. Keep them covered with a dry kitchen towel to stop them from drying out.
Line a bamboo or metal steamer basket with 2-3 cabbage leaves. Place the dumplings on the leaves, making sure they're not touching each other and are at least ½ inch apart from one another and 1 inch away from the edge of the basket.
Put the steamer basket over a pot of boiling water. Cover it and steam the dumplings on high heat until the pork inside is fully cooked and the wrappers look see-through, which should take about 5-7 minutes.
Once cooked, carefully take the dumplings out of the steamer. If you have more dumplings left to cook, repeat the previous step with new cabbage leaves and more boiling water as needed.
Serve the dumplings right away while they're still hot.
