Panko are bread crumbs used with batter to make deep-fried fritters. Fresh panko make the fritters lighter and softer than dried panko, as they contain more moisture which evaporates and forms small air holes when the panko are deep-fried. Lightly moistening dried panko just before cooking makes it more like fresh panko, and it should be applied evenly to the surface of the meat or fish being fried. To ensure freshness, dried panko should be stored in a dry, cool place.
