What is panko bread? i have never heard of this.
Japanese bread crumbs-check for them in international aisle or Asian grocery. They are kind of light and fluffy, really delicious and worth seeking out.
Many regular grocers now carry this excellent product so you don't have to go to an Asian specialty store any longer. They are not bread itself but large crumbs and they make an extremely light and crispy coating for anything fried.
Panko crumbs are a type of light "bread" crumbs, most often used in Asian cooking. They may be found in your local grocery in the bread aisle, in the baking aisle (maybe around the area of Shake and Bake), or with the Asian foods. Hope this helps you!
