A crispy crunchy mouth-watering preparation of thinly sliced pork deep fried and tossed with vegetables and a sweet and tangy sauce. The best ever Sweet and Sour Pork recipe is loaded with tricks the Chinese have been using for centuries: double dredge and double fry for extra crispy, cornflour instead of flour, economical pork used for juiciness, but tenderized with baking soda so you’d swear they’re pricey chops, and a sauce that’s not sickeningly sweet.
