How to make the perfect sweet and sour chicken and the common mistakes to avoid

Sweet and sour chicken is the perfect way to celebrate Chinese New Year.
Sweet and sour is delicious with pork, prawns and tofu, so don't be afraid to use the protein of your choice. Toss tofu in five-spice and cornflour and cook either on a frying pan or in an air fryer until crispy, add prawns to the sauce five minutes before serving and cut pork into 5mm thick pieces before cooking.
