Chop the ground pork with 2 tablespoons of cold water. Place the pork in a bowl. Add the chopped dry shrimp (soaked first to soften), chopped scallion, chopped ginger, soy sauce, salt, 1 tablespoon of cornstarch, and an egg. Mix well until the pork is very sticky.
Wash the glutinous rice and soak in cold water for about half an hour. Drain.
