This is going to sound like a skit from Portlandia so I apologize in advance.
We were early implementers of the Panko, least ways in this rural neck of the woods. My SIL would get them for us on her shopping forays to Atlanta. Now, they are mainstream, we can get Progresso Panko at our local grocery. Problem is, they aren't as good as the ones we used to get in a cellophane bag.
