In a large mixing bowl, add the cream cheese, crabmeat, scallions, Worcestershire sauce, sesame oil, sugar, garlic powder, onion powder, salt and white pepper. Mix well to combine. Set aside.
In a separate small dish, add and whisk together the egg and water. Set aside.
On a clean work surface, place down a sheet of egg roll wrapper. With a pastry brush, apply some of the egg wash along the (4) edges of the wrapper.
Scoop or spoon a portion of the filling mixture (about 2 ounces) into the center of the wrapper. Bring up the opposite ends of the wrapper to form a triangle. Gently press out any air pockets around the filling so that the wrapper is completely sealed around the filling.
Starting on one end of the triangle, fold the edge of wrapper on to itself to form a purse shape. Firmly press the folded edges together to seal.
Transfer crab rangoon to a parchment lined baking sheet and repeat with the remaining filling and wrappers for a total of (8) rangoons.
Heat up oil (about 3-4 cups) in a pot over medium heat to 350F. In batches, fry the rangoons until richly golden brown on all sides, about 4-5 minutes or longer as needed. Transfer to a paper towel lined plate or baking sheet to remove any excess oil.
Serve rangoons immediately while still warm and crispy with sweet chili sauce or your favorite sauce.
