Cut chicken wings into individual segments and remove wing tips.

In a shallow dish, whisk together cornstarch, eggs, and water until smooth.

Dip each chicken wing segment into the cornstarch mixture, ensuring it's fully coated.

Heat oil in a large pan or skillet over medium-high heat.

Place the coated chicken wings in the hot oil, being careful not to overcrowd the pan.

Fry the wings until golden brown and crispy on all sides, about 8-10 minutes.

Remove the fried wings from the pan and set aside.

In a separate saucepan, combine apple cider vinegar, sugar, ketchup, apple jelly, soy sauce, and lemon juice.

Bring the sauce to a simmer over medium heat, stirring constantly until the sugar and jelly are dissolved.

Pour the sweet and sour sauce over the fried chicken wings in the pan.

Reduce heat to low and simmer for 20 minutes, turning the wings occasionally to ensure they are evenly coated in the sauce.

Remove from heat and serve hot.
