 Most supermarkets across Europe and America carry a range of prepared sweet and sour sauces either for adding to a stir-fry or for use as a dipping sauce.Primarily in North America, sweet and sour sauce is available in small plastic packets or containers at Chinese take-out establishments for use as a dipping sauce.In Britain, Thai-style sweet chilli dipping sauce has recently overtaken the previous popularity of Chinese-style sweet-sour sauce to the extent it can often be found at non-Asian establishments for a wide variety of western-style snacks from fishcakes to chips and seafood such as calamari and prawns.
