Heat vegetable oil in a Dutch oven or large pot over medium high heat to 350 degrees F.

Season chicken wings with salt and pepper, to taste.

Working in batches, add the chicken wings to the Dutch oven, 5 or 6 at a time, and fry until light brown, about 2-3 minutes. Transfer to a paper towel-lined plate.

Increase oil temperature to 400 degrees F. Add the chicken wings to the Dutch oven again and cook until golden brown and crispy, about 2 minutes on each side. Transfer to a paper towel-lined plate.

Heat soy sauce and sugar in a small saucepan over medium high heat. Bring to a boil; reduce heat to low and simmer, stirring occasionally, until sauce has thickened, about 2-3 minutes.

Serve wings immediately, tossed with soy sauce glaze.
