This finger-licking sweet & sour chicken tastes exactly like a sweet & sour chicken from a Chinese restaurant! Easy to make foolproof recipe, amazing taste!
Put the sauce ingredients (sugar, apple cider vinegar, ketchup, Worcestershire sauce, soy sauce and Oyster sauce) in a microwave-safe bowl. Microwave on High for 1 minute, then stir with the spoon so the sugar is dissolved.
Cut the chicken into 1-inch pieces and put in another bowl.
Add the eggs to the chicken and toss to coat.
Take two 1-gallon ziploc bags and put 1 cup of cornstarch in each bag. Put half the chicken in each bag, zip the bags and shake them until the chicken is evenly coated with cornstarch.
Heat the oil in a large non-stick frying pan over medium-high heat.
Cook the chicken in batches (so it fits in the pan in a single layer without the pieces touching each other), stirring every minute, for 4 minutes. Removed cooked chicken in a bowl.
Put all cooked chicken back into a frying pan (all at once) and pour sweet & sour sauce over it. Heat over medium-high heat until the sauce starts boiling. Start stirring the chicken every 20 seconds until the sauce is thickened and all the chicken is evenly coated with sauce (about 4 minutes).
