Make the Filling - In a medium bowl, mix crab meat, cream cheese, chives, salt, and pepper.
Add the Filling - Add 1 tablespoon (15g) of crab filling into the center of the wonton wrapper. Lightly brush the edges of the wonton wrapper with water. Bring the two opposite points together and press the corners together.
Seal the Wonton - Bring the other opposite edges together to create a purse shape. Seal the long side edges together, removing as much air as possible. Repeat with the remaining wonton wrappers.
Deep Fry the Wontons - Heat vegetable oil in a large pot, dutch oven, or wok until it reaches 350ºF (177ºC), do not exceed 375ºF (191ºC). Deep fry crab rangoon wontons, 4 at a time, until golden brown and crispy, about 1 to 1 ½ minutes. Use a metal spider strainer or a large spoon to submerge the wontons for even cooking. Check the color change visually for the best indication of when the wontons are done.
Cool After Frying - Transfer fried wontons to a sheet pan topped with a cooling rack or lined with a paper towel to drain excess oil. Repeat frying with the remaining wontons.
To Serve - Pair with the desired dipping sauce like sweet and sour sauce.
Notes
Filling Size: Use 2 to 3 teaspoons of crab filling for each wonton.
Crab Meat: Imitation crab may also be used.
Wonton Wrapper: Use square wontons measuring 3 1/2 by 3 1/2 inches.
Watch the Oil Temperature: If it goes above 375ºF (191ºC), the wontons will fry quickly, within 30 seconds.
Alternative Folding Techniques: You can also create a triangle-shaped fold or a tortellini shape with the filled wonton wrapper.
