How to Make It
In a small bowl, combine the wine and soy sauce. Add the pork and stir to coat. Let stand at room temperature for at least 30 minutes and up to 1 hour.
In a medium saucepan of boiling water, cook the snow peas until bright green, about 1 minute. Drain, refresh under cold running water and drain again.
Set a large wok over high heat until very hot. Add the oil and swirl to coat. When the oil is hot, add the scallions and garlic and stir-fry for 30 seconds. Add the pork and any remaining marinade and stir-fry until the meat changes color, 1 to 2 minutes. Add the snow peas and stir-fry for 30 seconds, then add the broth, sugar and salt. Cover and cook for 1 minute. Add the cornstarch mixture and cook, stirring occasionally, until the sauce thickens, 1 to 2 minutes. Remove from the heat, transfer to a platter and serve hot.
