Panko is the Japanese word meaning "bread crumbs or child or bread". They are made from the soft, tender centers of bread instead of the crust. They supposedly form a lighter texture and are less dense. They are now popular with chefs everywhere. I am withholding my opinion until I try them.
I plan to make my next batch of Sicilian meatballs with them. I will report the results. It must be a cross between using fresh broken up pieces of bread and regular bread crumbs.
