Does anyone know which shop sells a nice sweet and sour sauce? Something like the type that McD's give out with their grub. I used to be able to get one ... I think it was HP that did it. There are plenty of stir fry s&s sauces, and Amoy do a dipping sauce but its just not the same as being able to pour it from a bottle, like tomato ketchup, and dip your chips in it.
