Coat the Pork with the Cornstarch and deep-fry over low-medium heat until no pink remains. Remove to a bowl for the moment.
Drain the pan of all but a tablespoon or two of oil and quickly pan-fry the Cashews until they just begin to turn brown in a few spots.
Turn the heat to medium high and fry the Ginger for a few seconds, followed by the Chili and the meat.
Stir together the Soy Sauce, Rice Wine, Sugar and Sesame Oil, and, when the Pork begins to brown in a few spots add the sauce mix to the pan along with the Cashews.
Stir-fry until the sauce mix forms a glaze, then serve immediately.
