Hi! I'm trying to make a family recipe that calls for rye chips. They are a savory rye bread cracker, kind of shaped like pringles. In WI the brand Pinah's is available and it looks like there might be a Gardetto's brand in the Chicago area, but I have no idea what stores, if any, carry them. So far I've tried Mariano's and searching the internet, to no avail. Any help?
