Crispy fried wontons with sweet and sour dipping sauce are a crowd-pleasing appetizer. A protein-rich, family party favorite with fresh, tangy flavor.
Finely chop the green onions and grate the carrot; place them in a mixing bowl with the ground pork.
Add the egg, soy sauce, sesame oil, salt, black pepper, and half the sugar to the bowl; mix well until fully combined and sticky.
Lay out a wonton wrapper, place about 1 teaspoon filling in the center, dampen the edges with water, and fold to seal firmly, pressing out the air. Repeat with remaining wrappers.
Heat vegetable oil in a deep skillet or wok to 350°F (medium-high heat). Fry wontons in batches for 2-3 minutes, turning occasionally, until golden brown and crispy. Remove and drain on paper towels.
For the sauce: In a small saucepan, combine remaining sugar, rice vinegar, ketchup, water, and cornstarch. Bring to a simmer over medium heat, stirring until thickened and glossy.
Serve fried wontons hot with the warm sweet and sour dipping sauce on the side.
