I couldn’t find a 16 oz. can, so I bought two 12 oz. bottles instead. We used all of one and part of the other. Interestingly, although both labeled “sweet and sour sauce,” one was more orange (a duck sauce type) and the other more red (tomato based). I actually really liked the combination. You could also make your own sweet and sour sauce. Here’s one recipe I found from a quick Google search – The Best Sweet and Sour Pork Meatballs.
