These are also similar, but not exactly. Also appears these are a type of Indian food? Not sure small town Iowa would be venturing into what would be considered quite exotic at that time. (hell, for that area it would still be considered quite exotic, LOL)Fryums? Come in different shapes and flavors.
It is a good guess though. As both the above prawn chips and these have certain aspects that would be similar. I'm sure someone else had to have had them too, but if they did stop making them all together when they became unavailable where I got them, its been a long time.
But we are definitely in the ballpark.
