Panko breadcrumbs are a type of breadcrumb used in Japanese cuisine. They are made from white bread that is processed into large, flaky crumbs, resulting in a light and crispy texture. Unlike traditional breadcrumbs, which are often fine and dense, panko provides a crunchier coating for fried or baked foods. These breadcrumbs are commonly used to coat tempura, tonkatsu, and other fried dishes, enhancing their texture and flavor. Panko can also be used as a topping for casseroles or mixed into meatballs and meatloaf for added crunch. They are available in most grocery stores and can be found in both plain and seasoned varieties.
