In a bowl, mix the cream cheese and scallions until well combined. Season with salt and pepper.
Place about 1 teaspoon in the center of a wonton wrapper. (Keep remaining wrappers covered with a damp paper towel until ready to use.) Moisten edges with water; fold one corner over the filling into a triangle and press the edges to seal. Repeat with other Rangoons.
In a saucepan, heat the oil between 325 to 350°F. Fry the Rangoons in batches, until golden brown, about 1 minute on each side. Drain on paper towels to drain excess grease before serving.
Notes
Make sure no air remains inside the wonton. As you fry the rangoon any air inside will turn into steam and break open the wonton leaving the oil covered with the filling.
Make sure the oil is at 350 degrees, lower will cause oily food. Too high will result in a quickly burned crab rangoon.
