Add the shrimp to the body of a food processor fitted with the blade. Pulse until the shrimp is pureed.
In a large mixing bowl add the pork, shrimp, soy sauce, rice wine, granulated sugar, ginger, garlic, cilantro, cornstarch, fish sauce, pepper and salt. Gently mix with your hands until just combined.
Working one wrapper at a time, place 1 teaspoon of filling in the center, brush the edges with the egg, and fold the wrapper in half, forming a triangle.
Next, overlap the opposite corners, brushing with egg to seal together. Repeat with the remaining wrappers until all of the pork mixture has been used.
Bring a large pot of salted water to a boil over medium heat. Working in batches, add the wontons and cook, until firm and cooked through, about 5 minutes.
Remove with a slotted spoon to plate. Continue until all of the wontons have been cooked.
